ML4875ES-5 Datasheet PDF - Micro Linear Corporation

GENERAL DESCRIPTION
The ML4875 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 ML4875 ideal for 1 cell applications. The ML4875 is capable of start-up with input voltages as low as 1V and is available in 5V, 3.3V, and 3V output versions with an output voltage accuracy of ±3%.

FEATURES
■ 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
■ 5V, 3.3V, and 3V output versions
