AN8021L, AN8021SB
AC-DC switching power supply control IC
s Overview
The AN8021L and AN8021SB are ICs which are 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 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.
