Typical application circuit
Features
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.
