FR1 is used to protect for the component failure or some excessive short events, also it can restrain the inrush current. 100kHz to avoid the frequency noise disturbing to data sample in power meter application. C11 is the power supply capacitor and C12 is the decoupling ceramic cap to decouple the voltage noise spike. C12 should be located near to IC. R22, R23 are the sense resistors with 1% tolerance for peak current setup. R15, R16, R21 and R24 are configured for input over voltage protection. C15 is used to filter the input voltage noise disturbance. The CX1, CX2 and LX1 compose the EMI filter to guarantee the conducted EMI meet the EN55022 criteria. CX1 is in series with CX2 for 420VAC input. R3, R8 and R11 are used to discharge the energy stored in CX1 and CX2 in 1 second for safety requirement. C1, C3, C9 are the output filter capacitor to restrain the output voltage ripple. One filter could be used for strict voltage ripple requirement. D3, D4, D7 and D8 compose the input stage to commute the AC voltage to DC voltage. R1, R4 are dummy load to regulate the output voltage within designed value. The C6 and C8 are used for energy storage reducing line noise and protecting against line surge. R2, R6, R10 and R12 is for balancing the voltage of C6 and C8. R14, R25 are configured to set the output voltage. U1, U3, R19 and C13 compose the control loop to feedback the output signal to FB pin and guarantee the quick control loop response and system stability. R7, C4 and D5 are formed the RCD to restrain the high voltage spike to protect the MOSFET. R20 is for switching frequency setup. Normally, the switching frequency is configured around Input Line wire is connected to GND(L) of main output for input AC frequency sample in power meter.
