A8483 Product details

Description

Pin Functions VIN.Supply to the control circuit.A bypass capacitor, C1, must be connected from close to this pin to GND.GND.Ground reference connected directly to the ground plane.The feedback resistor should have a separate connection directly to this point.EN.Voltage lower than 0.4 V disables the A8483 and puts the control circuit into the low-power sleep mode.Voltage greater than 1.5 V fully enables the A8483. SW.Low-side switch connection between the inductor, L1, and ground.Becaus
