Power Management solution for Altera Arria 10 FPGA

Question Could you please advise, what is ADIs preferred PMIC solution for Altera Arria 10 FPGA. Answer Unfortunately the datasheet is still preliminary and we would need to know which version and usage case (processor speed, logic gate used transceivers datarates, etc) to determine the current requirements. As far as voltage and sequencing we can easily meet them with multiple products depending on their available power rails (12V or 5V or other?). Also they would have to use the Altera EPE tool to determine the detailed needs (see the copied section below Table 6). Table 6 listed the voltage requirements which are easy to achieve with products like the ADP5052/4. Your customer may be interested in the I2C version parts to adjust the core voltage. ADM717x would be recommended for the PLL supply (1.8V) as they have stringent phase noise requirements for the transceivers. So please introduce the ADP5052 & ADP5054 as multi-rail power solution for powering the Altera Arria 10 and the ADM7170/1/2 as the PLL supply. If you can get further details on the power supply requirements of the design we can try and put a more detailed solution together. www.analog.com/ADP5052 www.analog.com/ADP5050 www.analog.com/ADP5054 www.analog.com/ADM7170 www.analog.com/ADM7171 www.analog.com/ADM7172

How to handle the sequence in ADP5052?

Question How to handle the sequence in ADP5052? Answer Each channel in ADP5052 has individual precision enable with 0.8V accurate turn-on threshold, which allows one channel’s output can be tied to other channel’s enable input (through optional RC delay timer) to well control power-up sequence. The PWRGD signal can be used along with enable pin to generate the sequence as well. It is possible to create a rough power-down sequence by precision enable to program different UVLO threshold for each channel, a delay time between channels can be produced when input power supply plug out and discharged slowly. Active output discharge feature helps the output capacitor discharge quickly to well control power down sequence. Just be noted it is difficult to produce the power-down sequence if the power supply discharges too quickly.

Is it possible to order a version with factory programmed output voltages?

Question Is it possible to order a version with factory programmed output voltages? Answer No, the ADP5052 is offered as adjustable output as default version. Refer to the ADP5052 datasheet for available factory programmable options including fixed output options, half switching frequency setting, PWRGD options and more. Please contact your local Analog Devices sales or distribution representative to order a device with options other than the default options. A minimum order quantity is necessary to create a new version product.

selecting an external FET?

Question How should a customer select an external FET? Answer Channel 1 and Channel 2 in ADP5052 integrate high-side power MOSFETs and low-side MOSFET drivers. External NFETs should be used in low-side power devices to achieve an optimized solution. Dual NFETs in a single package is highly recommended if the size of the solution needs to be reduced. Note that the MOSFET Rdson is related to the efficiency under heavy load. The small Qg is preferred to reduce switching loss and avoid the short-through issue. Generally Qg lower than 20nC is recommended for the ADP5052. The ADIsimPower tool can also help to choose the right NFETs according to customer requirements.

Typical markets/applications for the ADP5052

Question What are typical markets/applications for this device? Answer The ADP5052 uPMU is an ideal power companion for Processors, DSPs and FPGAs. It covers the most common multiple supply needs where the buck is typically used to supply the core voltage, IO rail, static memories and other peripherals, while the one LDO can power some analog circuitry which needs low power and noise immunity. The ADP5052 finds applications in a variety of markets requiring compact, reliable power supply and sequencing functions. Infrastructure, Industrial & Instruments, Consumer and Medical applications are examples where the ADP5052 can be successfully adopted.

Can the 4 bucks run at different frequency?

Question Can the 4 bucks run at different frequency? Answer No. the 4 bucks would run the same switching frequency by external RT resistor setting or synchronization with input clock. However, additional pre-defined configurations are possible upon request and as indicated in ADP5052 datasheet, Channel 1 and Channel 3 can be program to half of master frequency set by RT pin. This will require a minimum quantity to be ordered.

Customer programmable fuses on ADP5053?

Question I’m interested in using the factory fuses of the ADP5053. Can you provide me with further information/documentation on that topic. Can these fuses be programmed only by the Analog Devices or also by the customer? Answer The fuses are blown at final test. We only have one model available, ADP5053ACPZ : www.analog.com/ADP5053 There is no user/customer programmable version.

Are there any layout considerations when designing in the ADP5052?

Question Are there any layout considerations when designing in the ADP5052? Answer Since the buck operates up to 1.4MHz it is important to follow some important rules when designing the PCB layout. In order to minimize the EMI it is important to place the buck input capacitor as close as possible to PVINx and PGNDx pins. Make sure also to use short connections for all the passive components, the ADP5052 pin-out is designed to facilitate this. Whenever possible use solid ground and power planes avoiding cutouts, use several vias connecting the thermal pad to the inner ground plane to facilitate power dissipation, exposed copper (on the top and bottom sides) is more effective in removing heat. Make sure that the switching circuit is not placed close to noise sensitive circuit especially RF to avoid magnetic coupling.

What’s the big differentiation for ADP5052 in the market?

Question What’s the big differentiation for ADP5052 in the market? Answer Power density, scalability and flexibility are three key differentiations for ADP5052 in the market. High power density: ADP5052 integrates four high performance buck regulators (4A, 4A, 1.2A, 1.2A) and one 200mA LDO in a 48-lead LFCSP package, delivering 5 rails (up to 25W output power) in relative small 588 mm^2 solution size provides a very attractive solution. High scalability: Channel 1 and Channel 2 in ADP5052 can be programmed to be 1.2A, 2.5A or 4A output, and different components selection can be achieved to optimize solution size, cost and performance. Combing channel 1 and channel 2 can provide a single output with up to 8A of current, which can easily meet higher load demand in system. High flexibility: easy sequencing, programmable SS timer, programmable switching frequency, synchronization input/output, FPWM or PSM operation mode setting, programmable current limit and other features provide high flexibility for ADP5052 applications.

How can I disable one channel when I don’t’ use it?

Question How can I disable one channel when I don’t’ use it? Answer If you don’t use one channel, for example dummy Channel 4, pull PVIN4, EN4, COMP4 and FB4 pin to ground, and leave SW4 and BST4 pin floating.

Can you use an inductor not specified in the datasheet?

Question Can you use an inductor not specified in the datasheet? Answer In general yes, although it is important to evaluate the characteristics of the inductor considered. The DCR (DC resistance) will affect the efficiency as the load current increases, while the core losses affect the efficiency at lower load currents. The saturation current must be sufficient to handle the load current plus the ripple current due to charge/discharge cycle into the inductor. Please refer to the ADIsimPower tool to select inductor base on detail design requirements.

Can you supply PVIN1, PVIN2, PVIN3, PVIN4 and PVIN5 independently?

Question Can you supply PVIN1, PVIN2, PVIN3, PVIN4 and PVIN5 independently? Answer PVIN1 supplies an internal housekeeping circuit and must be tied to input voltage. PVIN2 and PVIN3, PVIN4 can be independently supplied from a voltage ranging from 4.5V to 15V.PVIN5 witch LDO input voltage range is 1.7V to 5.5V.
