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.

Key Features

s Guaranteed full load start-up and operation at 1.8V input Continuous conduction mode for high output current Very low supply current (20µA output referenced) for micropower operation Pulse Frequency Modulation and Internal Synchronous Rectification for high efficiency Maximum switching frequency > 200kHz Minimum external components Low ON resistance internal switching FETs Adjustable output voltage (3.0V to 5.5V) s s s s s s s (.
Indicates Part is End Of Life as of July 1, 2000) BLOC.
