Detailed description

ACE723A is a 3A synchronous buck, with frequency adjusted by Ren_. It can achieve conversion

efficiency up to 95%. It also support 100% duty cycle which will maximize the battery usage. Only a

inductor and a few R & C need for peripheral. The PCB size can be very small

Please note that EN_ pin has to be pull high if one wants to shutdown the chip. And release it (with a

Ren_ connected to GND) to have it work.

One can also switch off ACE723A by connect enable signal

with at least 1mA driving capability to VDD pin (pin 6 of DFN2x2 and pin 8 of DFN3x3 package).
