Available in a QFN20 (3x4mm) Package

To futher optimize efficiency at light load, the V_CC

supply of MP38900 is designed to be biased

externally.

APPLICATIONS



Notebook Systems and I/O Power

Networking Systems

Optical Communication Systems

Distributed Power POL Systems

Constant-On-Time (COT) control mode provides

fast transient response and eases loop

stabilization.

Full protection features include SCP, OCP, OVP,

UVP and thermal shutdown.
