AN8021L and AN8021SB are ICs suitable for controlling the 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.
The Panasonic AN8021L and AN8021SB are integrated circuits designed for controlling switching power supplies using the primary side control method. These ICs are optimized for relatively small capacity power supplies, offering a compact design with minimal peripheral components to reduce costs. They operate at a control frequency up to 700 kHz and feature a pre-start operating current as low as 70 µA, allowing for the use of miniaturized start resistors.
| Control Frequency | Up to 700 kHz |
|---|---|
| Output Rise Time | 35 ns |
| Output Fall Time | 25 ns |
| Absolute Maximum Peak Output Current | +1.0 A |
| Packages | 9-pin SIP, 16-pin SOP |
They are ICs suitable for controlling the switching power supply using the primary side control method.
The ICs are available in two package types: 9-pin SIP and 16-pin SOP.
