产品概览
The onsemi NCP1200D060R2G is a PWM current-mode controller designed for low-power universal off-line SMPS, operating at a fixed 60 kHz switching frequency. Housed in an SOIC-8 package, it features skip-cycle capability for excellent light-load efficiency, self-supply operation from the DC rail, and internal leading-edge blanking — combining compact design with robust protection for AC-DC adapters and battery chargers.
