ML4861*
Low Voltage Boost
Regulator
GENERAL DESCRIPTION
The ML4861 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 ML4861 ideal for 1 cell applications.
The ML4861 is capable of start-up with input voltages as low as 1V and is available in 6V, 5V, and 3.
3V output versions with output voltage accuracy of ±3%.
An integrated synchronous rectifier eliminates the need for an...
