AP1400

[AP1400] AP1400 2 cell, Multi-channel System Power Control IC 1. General Description The AP1400 is a multichannel system power supply IC that has a 4ch DC-DC converter and a 2ch LDO, supporting input voltage up to 12V. It integrates a start sequence circuit, a current sense circuit, an external load switch control circuit, and various protection functions. A power supply system can be simply designed with the AP1400. In addition, the standby current is very low at 19 μA. The AP1400 is housed in a small 65-pin WLCSP package, making it ideal for portable equipment such as digital single lens reflex cameras and mirrorless cameras.  Operation Input Voltage  Startup Sequence 2.
