1 A, 20V PWM DAC present supply with monitoring preregulator
This design concept reprises one other “1A, 20V, PWM managed present supply.” Like the sooner circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 A present supply. It income from the correct inner voltage reference and overload and thermal safety options of this time confirmed…
