ML4865 - High Voltage High Current Boost Regulator

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.

Features

  • Guaranteed full load start-up and operation at 1.8V input Continuous conduction mode for high output current Very low quiescent current Pulse frequency modulation and internal synchronous rectification for high efficiency Maximum switching frequency > 200kHz Minimum external components Low ON resistance internal switching FETs Fixed 12V output can be adjusted to lower output voltages General.
