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 func-

tions are removed, and only the necessary minimum func-

tions 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 de-

creasing the peripheral parts.

s Features

• It operates at a control frequency up to 700 kHz, realiz-

ing 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 against malfunction at low

voltage (on/off: 14.2 V/9.2 V)

• Maximum Duty is 44% (typical)

• Equipped with timer latch function and overvoltage pro-

tection circuit.

• Two kinds of packages: 9-pin SIP, 16-pin SOP

s Applications

• Various power supply equipment
