Using a load-monitoring IC (MAX4210), it senses the load current and load voltage independently, and multiplies the corresponding signals together with an internal analog multiplier. Applying the multiplier output to the inverting input of an error amplifier lets you apply a control voltage to set the constant-power level. This design idea appeared in the December 15, 2006 issue of Electronic Design magazine. Supplying a fixed and accurate power level to……
