LC2332无线充2A降压电源芯片

DESCRIPTION
 

The LC2332 is a fully integrated, high-efficiency 2A synchronous rectified step-down converter. The LC2332 operates at high efficiency over a wide output current load range.

 

This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load.

 

The LC2332 requires a minimum number of readily available standard external components and is available in a 6-pin SOT23 ROHS compliant package.
