IC QR-ZVS FLYBACK CONTROLLER 8SO


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardQuasi-resonant zero-voltage-switching flyback controller IC designed for offline AC-DC power supplies. Features line feedforward compensation, frequency foldback for standby efficiency, pulse-by-pulse current limiting with hiccup-mode overcurrent protection, and ultra-low startup/quiescent currents. Integrates error amplifier, gate driver, and zero-current detector for efficient power conversion in adapters, monitors, and consumer electronics.
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
