Advance Datasheet Low-Power Off-line Primary Side Regulation Controller AP3772 The AP3772 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. The AP3772 provides accurate constant voltage, constant current CV/CC regulation without requiring an opto-coupler and the secondary control circuitry. It also eliminates the need of loop compensation circuitry while maintaining good stability. The AP3772 can achieve excellent regulation and high average efficiency, yet meets no-load consumption less than 30mW. It can also achieve excellent dynamic performance while maintaining 30mW standby power with AP4340. The AP3772 has a built-in fixed cable voltage drop compensation function. The magnitude of the cable compensation voltage is set as 6%, 3% and 0 of the rated output voltage respectively to meet various cables with different length and gauge. It also has an adjustable built-in line compensation function to achieve tight CC. The AP3772 is available in SOT-23-6 package. • Primary Side Control for Tight Constant Current and Constant Voltage • 30mW No-load Input Power • Excellent Dynamic Performance with AP4340 • Bipolar Junction Transistor BJT Driving • Proprietary Adjustable Line Compensation for CC Variation • Constant and Built-in 6%, 3% and No Cable Voltage Drop Compensation • Enhanced Audio Noise Suppression • Open Circuit Protection • Over Voltage Protection • Short Circuit Protection • SOT-23-6 package • Adapters/Chargers for Cell/cordless Phones, PDAs, MP3 and Other Portable Devices • LED Driver • Standby and Auxiliary Power Supplies SOT-23-6 Figure Package Type of AP3772 BCD Semiconductor Manufacturing Limited Advance Datasheet Low-Power Off-line Primary Side Regulation Controller AP3772 Pin Configuration K6 Package SOT-23-6 Pin 1 Mark Figure Pin Configuration of AP3772 Top View Pin Description Pin Number 1 2 3 4 5 6 Pin Name OUT GND VCC CS CPC FB Function BCD Semiconductor Manufacturing Limited 2 Advance Datasheet Low-Power Off-line Primary Side Regulation Controller AP3772 Functional Block Diagram UVLO OVP & OCKP 0.1V COMP Tonsec Detector Dynamic Response PRO TONS VCC 3 Ordering Information AP3772 Circuit Type Cable Compensation Voltage A 6% B 3% C 0 Package K6 SOT-23-6 G1 Green TR Tape & Reel Package SOT-23-6 Temperature Range -40 to 85°C Cable Compensation Voltage 6% AP3772AK6TR-G1 AP3772BK6TR-G1 AP3772CK6TR-G1 Marking ID GKA GKB GKC Packing Type Tape & Reel Tape & Reel Tape & Reel BCD Semiconductor's Pb-free products, as designated with "G1" suffix in the part number, are RoHS compliant and green.
