ML4866 Datasheet 3.3v Output DC-dc Step-down Converter

Manufacturer: Micro Linear

Overview: July 2000 ML4866* 3.3V Output DC–DC Step-Down Converter GENERAL.

General Description

The ML4866 is a high efficiency pulse width modulated (PWM) buck regulator designed for use in 5V systems or portable equipment that need a compact, efficienct 3.3V supply.

It has a switching frequency of 120kHz and uses synchronous rectification to optimize power conversion efficiency.

Unlike other solutions, the ML4866 requires no external diodes or FETs.

Key Features
