DESCRIPTION
AP8012A is a high performance offline PSR power switch for low power AC/DC charger and adapter applications. It operates in primary‐side sensing and regulation.
Consequently, opto‐coupler and A431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control isintegrated as shown in the figure below.
In CC control, the current and output power setting can be adjusted externally by the sense resistor Rs at CS pin. In CV control, multi‐mode operations are utilized to achieve high performance and high efficiency. In addition, good load regulation is achieved by the built‐in cable drop compensation. Device operates in PFM in CC mode at large load condition and it operates in PWM with frequency reduction at light/medium load.
The chip consumes very low operation current. It achieves less than 75mW standby power to meet strict standby power standard.
AP8012A offers comprehensive protection coverage with auto‐recovery feature including Cycle‐by‐Cycle current limiting, VDD over voltage protection, feedback loop open protection, short circuit protection, built‐in leading edge blanking, VDD under voltage lockout (UVLO), OTP etc.
APPLICATIONS
Low Power AC/DC offline SMPS for
Industrial instruments: single / three‐phase meters
Outdoor monitoring / protection equipment
AC / DC with high input voltage
