ML4894 Datasheet (Micro Linear) - Synchronous Buck Controller

ML4894, Synchronous Buck Controller

The ML4894 synchronous buck controller has been designed to provide high efficiency DC/DC conversion for portable products.

The ML4894 can deliver a fixed 5V output from input voltages of 5.9V to 15V.

The ML4894 drives external P- and N-channel MOSFETs in a synchronous buck topology, allowing an ove
