General Description

The ML4775 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 ML4775 ideal for 1 cell applications.

The ML4775 is capable of start-up with input voltages as low as 1V, and the output voltage can be set anywhere between 2.5V and 5.5V by an external resistor divider connected to the SENSE pin.

Key Features

s s s s s s s Guaranteed start-up and operation at 1V input 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 Micropower operation Adjustable output voltage (2.5V to 5.5V) BLOCK.
