GENERAL DESCRIPTION

The ML4950 is a low power boost regulator designed for low voltage DC to DC conversion in single cell battery powered systems. The maximum switching frequency can exceed 100kHz, allowing the use of small, low cost inductors.

FEATURES

■ Guaranteed full load start-up and operation at 1V input

■ Pulse Frequency Modulation (PFM) and internal synchronous rectification for high efficiency

■ Minimum external components

■ Low ON resistance internal switching FETs

■ Micropower operation

■ Adjustable output voltage (2V to 3V)

■ Low battery detect
