FSD210 can meet low standby power under 0.1W at 265Vac & no load Standby power of FSD200 is higher because it’s internal start-up block connected to rectified AC line consumes power more FSD200(rectified AC line max 375Vdc*Iop) vs. FSD210(Vcc bias winding max 20V*Iop)

• The built in startup provides trickle current until the supply reaches a present supply voltage threshold called Vstart

• Switching starts and the peak current is gradually ratcheted up in fixed increments over a milliseconds

• This soft startup mechanism helps prevent high current during startup from damaging the components in the SMPS
