AN8022L

AC-DC switching power supply control IC; ? 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.\n? Pre-start operating current is as small as 70 μA (typical) so that it is possible to miniaturize the start resistor.\n? Output block employs totem pole method. The absolute maximum rating of ±1.0 A (peak) allows the direct drive of power MOSFET.\n? Built-in pulse-by-pulse overcurrent protection circuit\n? Built-in protection circuit against malfunction at low voltage (on/off: 14.2 V/9.2 V)\n? Maximum Duty is 44% (typical)\n? Equipped with timer latch function and overvoltage pro tection circuit.\n? Two kinds of packages: 9-pin SIP, 16-pin SOP■ Applications\n? Various power supply equipment?;

■ Overview\nThe AN8022L and AN8022SB are ICs which are suitable for controlling a switching power supply using primary side control method.\nThose are most suited for a switching power supply of relatively small capacity. Less frequently used functions are removed, and only the necessary minimum func tions are incorporated, so that they are compact and very easy to use.\nMoreover, the internal settings are incorporated as much as possible, thus cost down can be realized by decreasing the peripheral parts.■
