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.
