LP6343 Datasheet (Lowpowersemi) - 3A Step-down Converter

LP6343, 3A Step-down Converter

The LP6343 contains a independent 1.5MHz constant frequency, current mode, PWM step-down converters.

The converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode.

The LP6343 is ideal for powering portable equipment that runs from a single
