ML4871
High Current Boost
Regulator
GENERAL DESCRIPTION
The ML4871 is a continuous conduction boost
regulator designed for DC to DC conversion in multiple cell battery powered systems.
Continuous conduction allows the
regulator to maximize output current for a given inductor.
The maximum switching frequency can exceed 200kHz, allowing the use of small, low cost inductors.
The ML4871 is capable of start-up with input voltages as low as 1.
8V and is available in 5V and 3.
3V output versions with an output voltage accuracy of ±3%.
An integrated synchronous rectifier eliminates the nee...
