... The AMC3202 develops a 1.276V reference from the FB pin to ground. Output voltage is set by connecting the FB pin to an output resistor divider and the maximum output voltage is determined by the VSW pin maximum voltage minus the output diode forward voltage. Referring to typical application circuit, the output voltage is set by the below formula (1): ⎛ ...

... P Soft Start Through the addition of an external circuit, a soft-start function can be added to the AMC3202. Soft-start circuitry prevents the COMP pin from slamming high during startup, thereby inhibiting the inductor current from rising at a high slope. Referring to the figure shown in the following, the soft-start circuitry requires a minimum number of components and allows the soft-start circuitry to be activated any time when the EN pin is used to restart the converter ...
