This is a ADP1821 Step Down DC-to-DC Converter circuit.
This circuit uses ADP1821 that is synchronous pulse-width-modulated (PWM), step-down controller, inexpensive and versatile.
It can drive all N-channel power stage to regulate an output voltage as low as 0.6 V.
WILL THIS DIM? OR CONTROL LIGHT OUTPUT OF A led LIGHTING SETUP ie: a led set of foglight bulbs, lightbar, pod-lights, etc on auto 12vDC setups?
