FSD210, FSD200 Typical application circuit
Features
- High efficiency (>67% at Universal Input)
- Low zero load power consumption (<100mW at 240Vac) with FSD210
- Low component count
- Enhanced system reliability through various protection functions
- Internal soft-start (3ms)
- Frequency Modulation for low EMI Key Design Notes
- The constant voltage (CV) mode control is implemented with resistors, R8, R9, R10 and R11, shunt regulator, U2, feedback capacitor, C9 and opto-coupler, U3.
- The constant current (CC) mode control is designed with resistors, R8, R9, R15, R16, R17 and R19, NPN transistor, Q1 and NTC, TH1. When the voltage across current sensing resistors, R15,R16 and R17 is 0.7V , the NPN transistor turns on and the current through the opto coupler LED increases. This reduces the feedback voltage and duty ratio. Therefore, the output voltage decreases and the output current is regulated.
- The NTC(negative thermal coefficient) is used to compensate the temperature characteristics of the transistor Q1. 1.

FSD210, FSD200 Typical application circuit
- Non isolation buck converter
- Low component count
- Enhanced system reliability through various protection functions Key Design Notes
- The output voltage(12V) is regulated with resistors, R1, R2 and R3, zener diode, D3, the transistor, Q1 and the capacitor, C2. While the FSD210 is off diodes, D1 and D2, are on. At this time the output voltage, 12V , can be sensed by the feedback components above. This output is also used with bias voltage for the FSD210.
- R, 680K, is to prevent the OLP(over load protection) at startup.
- R, 8.2K, is a dummy resistor to regulate output voltage in light load. 1. Schematic 2.
