ML4875 - Low Voltage Boost Regulator with Shutdown

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.

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 5V, 3.3V, and 3V output versions.
  • Some Packages Are End Of Life Or Obsolete BLOCK.

July 2000 ML4875* Low Voltage Boost Regulator with Shutdown 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%. Unlike regulators using external Schottky diodes, the ML4875 isolates the load from the battery when the SHDN pin is high.
