LM2655 Datasheet (National Semiconductor) - 2.5A High Efficiency Synchronous Switching Regulator

LM2655, 2.5A High Efficiency Synchronous Switching Regulator

The LM2655 is a current-mode controlled PWM step-down switching regulator.

It has the unique ability to operate in synchronous or asynchronous mode.

This gives the designer flexibility to choose between the high efficiency of synchronous operation, or the low solution cost of asynchronous operation.
