Overview

July 2000 ML4771* High Current Boost Regulator GENERAL DESCRIPTION The ML4771 is a continuous conduction boost regulator designed for DC to DC conversion in multiple cell battery powered systems.
Continuous conduction allows the regulator to maximize output current for a given inductor.
The maximum switching frequency can exceed 200kHz, allowing the use of small, low cost inductors.
The ML4771 is capable of start-up with input voltages as low as 1.
8V, and the output voltage can be set anywhere between 3.
0V and 5.
5V by an external resistor divider connected to the SENSE pin.
An integrated synchronous rectifier eliminates the need for an external Schottky diode and provides a lower forward vo...
