General Description

The ML4851 is a low power boost regulator designed for DC to DC conversion in 1 to 3 cell battery powered systems.

The maximum switching frequency can exceed 100kHz, allowing the use of small, low cost inductors.

The combination of BiCMOS process technology, internal synchronous rectification, variable frequency operation, and low supply current make the ML4851 ideal for 1 cell applications.

Key Features

n Guaranteed full load start-up and operation at 1V input n Maximum switching frequency > 100kHz n Pulse Frequency Modulation (PFM) and internal synchronous rectification for high efficiency n Minimum external components n Low ON resistance internal switching FETs n Micropower operation n 5V and 3.3V output versions.
Some Packages Are Obsolete BLOCK.
