LC2332CB6TR无线充2A降压电源芯片LC2332

description

the lc2332 is a fully integrated, high-efficiency 2a synchronousrectified step-down converter. the lc2332 operates at highefficiency over a wide output current load range.

this device offers two operation modes, pwm control and pfm modeswitching control, which allows a high efficiency over the widerrange of the load.

the lc2332 requires a minimum number of readily available standardexternal components and is available in a 6-pin sot23 rohscompliant package.
