ML4775 Adjustable Output Low Voltage Boost Regulator with Shutdown
GENERAL DESCRIPTION
The ML4775 is a boost regulator designed for DC to DC conversion in 1 to 3 cell battery powered systems. The bination 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. Unlike regulators using external Schottky diodes, the ML4775 isolates the load from the battery when the SHDN pin is...
