AN8021NS External excitation flyback AC-DC switching power supply controller

Pin No. 1 2 3 Symbol VOUT VCC TIM/OVP Direct power MOSFET drive output Description Voltage Regulators Power supply. This pin monitored, and has threshold voltages for startup, stop, OVP reset, and other functions. OVP (overvoltage protection) and timer latch functions. OVP: Accepts a power supply.

Voltage Regulators AN8021NS External excitation flyback AC-DC switching power supply control IC s Overview The AN8021S is a switching power supply control IC that controls the power supply from the primary side. It is optimal for relatively small switching power supplies. All rarely used functions have been removed from the AN8021S and as a result it is an extremely easy-to-use compact device. Furthermore, internal settings are implemented as many as we can, cost cut is possible with reduced ex.

AN8021NS Features

* 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
