Hi,

There is a question about loop compensation of ADP1614.

Lower mentioning is in the data seat.

ADP1614 DS

For most applications, the compensation resistor should be…

ADP1614 boost voltage input 5V output 15V and following Evaluation Board User Guide UG-437 to do circuit desing ,during application that I having a problem of boost voltage to 15V will instant current consumption around 1.2A at beginning and after few…

Can someone explain the "extra" MOSFET in the CUK/SEPIC configuration of this circuit?  It is shown in the output of the Excel design tool, but it is not shown in app note AN-1106.

What is the largest capacitor that can be used on the Soft Start pin of the ADP1614? It contains an internal low-side switch to reset the capacitor in response to certain events (such as thermal shutdown) which implies that there is an upper board on…

Hi,

I am looking for a Boost Voltage Controller/Regulator that can provide the following

1) Input Voltage = 3.7V

2) Output Voltage = 5V

3) Output Current = 4A

Is it possible to connect two ADP1621/ADP1614 in parallel to get 4A?

Or

Can we connect…

Hi All,

My customer investigating low cost LED driver IC.

Is it possible to use ADP1614 as a LED Driver with its adjustable current limit function?

If yes, can I obtain reference circuit for 5 white LEDs in series?

Thank you for your support.

Best…

The above image shows the schematics of the two-stage boost conversion. 

Stage 1: Battery/Bench-top power supply to ADP1614 to obtain regulated 5V output. The 5V is then used for the following:

           a. It connects to an ADP7104 (P3 on the schematic) which…

咨询下，充电宝项目：使用ADP1614做了一个升压电路，3.7-4.2V电池输入，输出5V@2A（max）。电路外围器件的选型均按照数据手册进行选择，在为手机，PAD等进行充电时均正常使用，一旦使用电子负载进行产品测试时，进行出现输出不正常的现象，会瞬间跌落，有点类似于输出短路保护的样子。输出电流100mA，200mA等都测试过，都出现过这种现象。

  请帮忙分析下，为何在电子负载情况下，不能正常工作？ 非常感谢
