BCD AP3706MTR-E1 Primary side control ic for off-line battery charger Datasheet

Product Brief
PRIMARY SIDE CONTROL IC FOR OFF-LINE BATTERY CHARGERS
Description
Parametric Table
The AP3706 is a high performance AC/DC power supply
controller for battery charger and adapter applications.
The device uses Pulse Frequency Modulation (PFM)
method to build discontinuous conduction mode (DCM)
flyback power supplies.
Startup Current (µA)(Typ)
UVLO Threshold on/off (V) (Typ)
The AP3706 provides constant voltage, constant current
(CV/CC) regulation without requiring an opto-coupler
and secondary control circuitry. It also eliminates the need
of loop compensation circuitry while maintaining stability.
The AP3706 achieves excellent regulation and high power
efficiency, the no-load power consumption is less than
200mW at 265VAC input.
