DESCRIPTION
AP8022A 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 is
integrated as shown in the figure below.
Typical
lCC/CV Curve
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 AP8022A consumes very low operation
current. It achieves less than 75mW standby power
to meet strict s standby power standard.
AP8022A offers comprehensive protection
coverage with auto-recovery feature including
Cycle-by-Cycle current limiting, VDD over voltage
protection, feedback loop open protection, built-in
leading-edge blanking, VDD under voltage lockout
(UVLO), OTP etc.
The AP8022A is available in DIP7 packages.
APPLICATION
Low Power AC/DC offline SMPS for
Industrial instruments: single / three-phase meters
Outdoor monitoring / protection equipment
AC / DC with high input voltage
