ACE727C
600KHz, 16V, 2A Synchronous Step-Down Converter
Description
The ACE727C is a fully integrated, high– efficiency 2A synchronous rectified step-down converter. The
ACE727C operates at high efficiency over a wide output current load range.
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 ACE727C requires a minimum number of readily available standard external components and is
available in a 6-pin SOT23 ROHS compliant package.
