MA8920 datasheet

Description :

The MA8000 series is a power supply IC module that contributes to energy saving during standby. This product incorporates a control circuit and a main switch element, and can configure a partial resonance RCC converter with a small number of external components. High efficiency, low noise standby low power consumption can be realized by the conventional power supply design method.

Features
1. Power consumption is very low at micro loads. (Load power 50mW, input voltage AC 100V, input power 0.5W or less.)
2. High efficiency over a wide range of loads.
(Efficiency 80% or more at rated load.)
3. Feedback noise is very small.
(Vcci-class B compliant.)
4. The oscillation operation is stable even with a minute load.
5. With soft start function.
6. The number of electrical parts is small and the circuit configuration is simple.
7. As IC modules can be selected according to the input / output specifications, design method can be unified and design time can be shortened.
8. Adoption of a full mold package is advantageous for insulation design.
9. All-round input design is also possible.
