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
AN8022SB 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 p
