Hello, 

I'm designing a controlled voltage source for 4 channels using a LTC2974 to control four LT3012 LDOs.

My question it's about current sensing ports. In the datasheet defines how to measure the current with a shunt resistor that includes a filter…

Hello

The data sheet recommends connecting unused TSENSEn pins to GND.

However, the temperature sense inputs (TSENSEn) may be left floating.

In this case, the temperature reported on floating TSENSEn inputs will be the internal die temperature.

Are there…

Hi,Support team

I'm evaluating DC1978A(LTC2974 demo board kit).

Regarding PWRGD pin,There seems to be a delay of  >140 msec after all power rails goes up.

I tried "Mfr_config_all_pwrgd_off_uses_uv = 1" and "MFR_POWERGOOD_ ASSERTION_DELAY = 0ms"…

My question is regarding the DC1962C demo board. I'm using LT power play to communicate with it via the DC1613A programming pod. 

I looked at the schematic and saw for the LTC2974, the ASEL1 pin is tied LOW and ASEL0 is tied HIGH. The Address look…

Hello 

I'm designing a new system. I would like to use a PowerManager. 
I need to control the current and voltage of 4 supplies. 
Now I have seen, that I could use a LTC2977. It allows to use the odd channels to be configured as current sens. This would…

Hi there!

Does the Spice model of LTM4651 work?
I am using 4651 to make -12V from +24V but can't get the desired output.
The output is -0.6V with 0.5Vpp ripple and freq is about 15kHz but the switching freq is set to 1.1MHz.
All external parts have selected…

We would like to monitor all of our power path to external devices, for power management, diagnostic and fault isolation.

Most power path start from an isolating DCDC and then fan out to 3-5 outputs, we will have 48V,24V,12V DCDC all isolated from each…
