GENERAL DESCRIPTION
The ML4961 is a boost regulator designed for DC to DC conversion in 1 to 3 cell battery powered systems. The combination of BiCMOS process technology, internal synchronous rectification, variable frequency operation, and low supply current make the ML4961 ideal for 1 cell applications. The ML4961 is capable of start-up with input voltages as low as 1V, and the output voltage can be set anywhere between 2.5V and 6V by an external resistor divider connected to the SENSE pin.

FEATURES
■ Guaranteed full load start-up and operation at 1V input
■ Pulse Frequency Modulation and Internal Synchronous Rectification for high efficiency
■ Minimum external components
■ Low ON resistance internal switching FETs
■ Micropower operation
■ Adjustable output voltage (2.5V to 6V)
