ACE710
0.9V startup, 0.6A 3.3V/5V Synchronous Boost DC/DC Converter
Description
ACE710 is a high-efficiency, synchronous step-up switching regulators optimized for battery-powered
applications. It supports up to 0.6A load current and allows the use of small, low cost inductors and MLCC
capacitors.
The ACE710 starts up as low as 0.9V input voltage and it has true-shutoff function (shut off output to
zero voltage when EN pulled low) and real output short-circuit protection. These features make it ideal for
USB interface power supply.
Given its high efficiency, the ACE710 device is ideal for small portable applications powered by battery. It
consumes as low as 40uA (3V input /3.3V output) at zero load. And its current consumption is less than
1uA in shutdown mode.
