UM3500 Datasheet - Union Semiconductor

UM3500 - Synchronous Step-Down DC-DC Converter

The UM3500 is a 1.5MHz constant frequency, slope compensated current mode PWM step-down converter.

The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode.

It is ideal for powering portable equipment that runs from a single cell lithium
