AP8007
AC-DC PWM CONTROLLER
PRIMARY SWITCHING REGULATORS
DESCRIPTION
The AP8007 is a high performance AC-DC off‐line
controller for low power battery charger and adapter
applications with Universal‐input. It uses Pulse
Frequency and Width Modulation (PFWM) method
to build discontinuous conduction mode (DCM)
flyback power supplies.
The AP8007 utilizes primary‐side sensing and
regulation technology to provide accurate constant
voltage, constant current (CV/CC) regulation without
requiring an opto‐coupler and secondary control
circuitry. It also eliminates the need of external loop
compensation circuitry while maintaining stability.
The AP8007 achieves excellent regulation and high
average efficiency, yet meets the requirement for
standby power less than 150mW.
The AP8007 ensures safe operation with complete
protection against all fault conditions. Built‐in
protection circuitry is provided for output short
circuit, output over‐voltage, line under‐voltage, VDD
over voltage, feedback open and short, and over
temperature conditions.
Integrated line and primary inductance
compensation circuitry, the AP8007 provides
accurate constant current operation despite wide
variations in line voltage and primary inductance. It
has the built‐in cable voltage drop compensation
function.
The AP8007 is available in SOT-25 package.
