General Description

The ML4865 is a high voltage, 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 s Continuous conduction mode for high output current s Very low quiescent current s Pulse frequency modulation and internal synchronous rectification for high efficiency s Maximum switching frequency > 200kHz s Minimum external components s Low ON resistance internal switching FETs s Fixed 12V output can be adjusted to lower output voltages BLOCK.
