AN8038S - AC-DC switching power supply controller
Pin No.
Symbol 1 TR Description AN8038, AN8038S Transformer reset.
When a transformer reset is detected, i.e., a low level is input to this pin, the IC output goes high.
However, the transformer reset signal is ignored during the minimum off-period determined by the CF pin.
The maximum on-period
Voltage Regulators AN8038, AN8038S AC-DC switching power supply control IC with RCC local resonance circuit for improved conformance with energy conservation laws s Overview The AN8038 and AN8038S are self-excited AC-DC switching power supply control IC that adopt RCC local resonance control.
These ICs are designed to achieve high efficiency over a wide range of loads (light loads at the standby mode to heavy loads) for improved conformance with energy conservation laws, and support input level
AN8038S Features
* AN8038S 5.01±0.20
* Supports improved conformance with energy conser8 5 vation laws by providing two operating modes. With external resistors, it is possible to set the operating point at which the modes change over according to the load power, as shown below. 1.Continuous (RCC) mode 1 4 Hi
