Description

The ACE726C is a fully integrated, high-efficiency 2A synchronous rectified step-down converter. The

ACE726C operates at high efficiency over a wide output current loadrange.

This device offers two operation modes, PWM control and PFM Mode switching control, which allows a

high efficiency over the wider range of the load.

The ACE726C requires a minimum number of readily available standard external components and is

available in a 6-pin SOT23 ROHS compliant package.
