DESCRIPTION

The AP8836 consists of a Low Standby-Power

Quasi-Resonant (QR) Primary-Side controller and a

650V avalanche-rugged smart power VDMOSFET,

specifically designed for a high performance AC/DC

charger or adaptor with minimal external

components.

AP8836 operates in primary-side sensing and

regulation, so opto-coupler and A431 could be

eliminated. Because of internal HV Start-up circuit,

the system with AP8836 can achieve less than 50mW

standby power consumption (264VAC). In CV

mode, multi-mode and quasi resonant technique is

utilized to achieve high efficiency, avoid audible noise

and make the system meeting Energy star class VI.

Good load regulation is achieved by the built-in cable

drop compensation. In CC mode, the current and

output power setting can be adjusted externally by

the sense resistor at CS pin. AP8836 offers complete

protections including Cycle-by-Cycle current limiting

protection (OCP), over voltage protection (OVP), over

temperature protection (OTP) and CS open or short

protection (CSO/SP) etc.

The AP8836 is available in DIP8 and SOP8

packages.
