LC2332B
LC2332B is 16V 2A Synchronous PFM/PWM Buck Converter manufactured by LEADCHIP.
16V 2A Synchronous PFM/PWM Buck Converter
DESCRIPTION
The LC2332B is a high efficiency current-mode synchronous, 16V/2A buck converter. Its input voltage ranges from 4.2V to 16V and it provides an adjustable regulated output voltage from 1V to 12V while delivering up to 2A of output current.
The internal synchronous switches increase efficiency and eliminate the need for an external Schottky diode. The switching frequency is set to 500KHz. And the LC2332B will automatically switch between PFM and PWM mode based on the load current, thus to enhance the converter efficiency at light load.
The LC2332B is available in the SOP8 package.
