ACE709
0.9V startup, 1A True Shut-Off Synchronous Boost DC/DC Converter
Description
ACE709, is a high-efficiency, synchronous step-up switching regulators optimized for battery-powered
applications. It supports up to 1A load current and allows the use of small, low cost inductors and MLCC
capacitors.
The ACE709 starts up as low as 0.9V input voltage and it has true-shutoff function (shut off output to zero
voltage when CE pulled low) and real output short-circuit protection. These features make it ideal for USB
interface power supply.
Given its high efficiency, the ACE709 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.
