It can also achieve accurate constant voltage and constant current. FR1 and CR1 compose the input stage. FR1 is used to protect for the component failure or some excessive short events, also it can restrain the inrush current. C1, L1 and C2 compose π filter to guarantee the conducted EMI meet standard EN55022. R2, R3, D1 and C3 compose the snubber circuit to reduce drain-source voltage spike. CY1 is Y capacitor lowering common mode noise to make sure there is enough EMI margin. T1 is power transformer, the structure of which is also very important to pass EMI test. D3, C8, C9, and C10 compose the 12V output circuit. D3 is schottky diode for better efficiency. C10 is ceramic capacitor for lower output voltage ripple. U3 is a LDO for 5V output. R7 and C7 are used to depress the spike of schottky. R4, C5, C6 and D2 are used as Vcc power supply. R5 and R6 are resistor divider for detecting output voltage by sampling voltage on primary auxiliary winding. EV020-5-S-01B Rev.1.0 www.MonolithicPower.com 5/31/2016 MPS Proprietary Information.
