Pulse width modulated controller systems. Implementations may include: a microcontroller coupled with a memory, a switch controller coupled with the microcontroller, and a calibration unit. The calibration unit may include one or more comparators, one or more passive electrical components, and an encoder logic all operatively coupled together and coupled with the microcontroller and with the switch controller where the at least one comparator and the one or more passive electrical components are electrically coupled with a supply voltage to the semiconductor switch and with a load voltage (output voltage) from the semiconductor switch.

Systems and methods for pulse width modulated control of a semiconductor switch

In one embodiment, a power supply controller of a power supply system uses an algorithm to reduce the number of drive pulses to the output transistors under light load conditions. The algorithm groups the drive pulses to the output transistors into sets and removes some of the drive pulses for each set drive pulses issued by the controller. Each successive set removes additional drive pulses.
