Description	External excitation flyback AC-DC switching power supply controller
Datasheet	AN8021NS_PanasonicSemiconductor.pdf

Pin No.

Supports operation at switching frequencies up to 700 kHz and achieves a 35 ns output rise time and a 25 ns output fall time.
Extremely low pre-startup current consumption of 70 µA (typical) allows a significantly smaller startup resistor to be used.
Totem pole circuit structure adopted in the output block.
Output current absolute maximum rating of ±1.0 A (peak) for direct driving of power MOSFET.
Pulse-by-pulse overcurrent protection circuit.
