SPDC12L00010 5 Application information 5.1 Input voltage There are two voltage supply pins: VCC (pin L3), for controller voltage supply; VIN (bank 1), for power circuit voltage supply. VCC and VIN can be connected and supplied together; if VIN is ...
Page 18
Application information 5.4 Soft-start The soft-start phase begins when both VCC and VIN raise above their turn-on thresholds, otherwise the SS_INL pin is internally shorted to SGND. A ramp is generated at SS_INL pin during start-up, charging the external capacitor ...
