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.

Features

 Capable of Delivering 1A

 High Efficiency: Up to 92%

 Compatible with MLCC capacitor

 1.8MHz Switching Frequency

 Low dropout 100% Duty operation

 0.6V Reference for Low Output voltages

 True Shutoff and Short-Circuit Protection

 Logic Control Shutdown (IQ<1uA)

 Thermal shutdown and UVLO

Application

 MID / Tablet PC

 Portable Power Bank

 Smartphone OTG

 Toy

 Other portable device
