AP3968MTR-G1 DIODES AC-DC Controllers

The AP3968MTR-G1 is a primary-side regulation PWM controller from Diodes Incorporated, designed for low-power offline flyback converters in AC-DC adapters and battery chargers. For selection, verify input voltage for offline operation, constant voltage (CV) and constant current (CC) regulation accuracy, built-in high-voltage startup, switching frequency, output power capability, and operating temperature suitable for power supply applications. Features include primary-side sensing eliminating opto-coupler and TL431 for reduced BOM cost, cycle-by-cycle current limiting, overvoltage protection, short-circuit protection, thermal shutdown, and frequency shuffling for EMI reduction. Ideal for low-cost AC-DC adapters (battery chargers, wall adapters), auxiliary power supplies for appliances, LED drivers, and any low-power offline flyback converter requiring primary-side regulation for simplified design and lower component count.
