High Performance 12V/4A Adapter Charger with Offline Current Mode Controller KP201 and Synchronous Rectifier KP40512

KP201 is a high performance current mode PWM controller for offline flyback converter applications. The IC supports DCM and CCM operation mode.

KP40512 is a high efficiency and reliability secondary side synchronous rectifier switch, which supports DCM, QR, CCM operation mode and integrates 100V MOSFET.

The demo board of KP201+KP40512-D02 is typically designed for the application of 12V/4A with universal input (90-265Vac, 50/60Hz). The demo board can achieve high efficiency, low standby power loss and meet the EN55022B EMI standard.
