Controlling a 120 W halogen lamp with the L9610C dimmer
The L9610C lamp dimmer is used to control the brightness of vehicle headlamps using H4
type lamps (see
lamps: closing the switch it is a possible to reduce the average lamp voltage as desired:
If pin 5 is connected to ground the average lamp voltage is constant, even for supply
voltages in excess of 13 V.
