General Description

The ML4869 is a continuous conduction boost regulator designed for DC to DC conversion in multiple cell battery power 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 Pulse Frequency Modulation and internal synchronous rectification for high efficiency Isolates the load from the input during shutdown Minimum external components Low ON resistance internal switching FETs Low supply current 5V and 3.3V output versions Shutdown current = 1µA MAX s s s s s s s s BLOCK.
