General Description

The ML4895 synchronous buck controller has been designed to provide high efficiency DC/DC conversion for portable products.

The ML4895 can deliver a user programmable 2.5V to 4V output from input voltages of 5.9V to 15V.

The ML4895 drives external P- and N-channel MOSFETs in a synchronous buck topology, allowing an overall conversion efficiency of greater than 90% over an output current range exceeding three decades, with an output current capability of up to 5A.
