DESCRIPTION
FEATURES
The AP8366 consists of a Low Standby-Power
Quasi-Resonant (QR) Primary-Side controller and a
avalanche-rugged smart power VDMOSFET
(AP8366-A/B 700V, AP8366-C 800V), specifically
designed for a high performance AC/DC charger or
adaptor with minimal external components. AP8366
operates in primary-side sensing and regulation, so
opto-coupler and A431 could be eliminated.
Internal
VDMOSFET
Internal HV Start-up Circuit, Standby power
consumption < 30mW at 230VAC
Multi-mode and Quasi-Resonant technique
achieve high efficiency, meeting energy star
class VI
±5% CC Regulation at Universal AC input
Primary-side Sensing and Regulation without
A431 and Opto-coupler
Programmable Cable Drop Compensation
No-need
avalanche-rugged
smart
power
Because of internal HV Start-up circuit, the system
with AP8366 can achieve less than 30mW standby
power consumption (230VAC).
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
RCS at CS pin. AP8366 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.
