AN8022SB - AC-DC switching power supply controller

Datasheet Summary

Description

AN8022L Pin No.

AN8022SB Pin No.

Features

  • It operates at a control frequency up to 700 kHz, realizing the output rise time of 35 ns and the output fall time of 25 ns.
  • Pre-start operating current is as small as 70 µA (typical) so that it is possible to miniaturize the start resistor.
  • Output block employs totem pole method. The absolute maximum rating of ±1.0 A (peak) allows the direct drive of power MOSFET.
  • Built-in pulse-by-pulse overcurrent protection circuit.
  • Built-in protection circuit.

Voltage Regulators AN8022L, AN8022SB AC-DC switching power supply control IC s Overview The AN8022L and AN8022SB are ICs which are suitable for controlling a switching power supply using primary side control method. Those are most suited for a switching power supply of relatively small capacity. Less frequently used functions are removed, and only the necessary minimum functions are incorporated, so that they are compact and very easy to use. Moreover, the internal settings are incorporated as much as possible, thus cost down can be realized by decreasing the peripheral parts. 9 8 6 21.7±0.3 0.5±0.1 7 5 4 3 2 1 1.0±0.25 2.7±0.25 4.3±0.3 0.3 –0.05 +0.1 2.
