[SM6VFZ] designed, built and tested a switched-mode DC-DC boost regulator using the core ... and a controller that can measure the output voltage, control the switching element and add safety ...

This is a boost DC/DC switching controller that adopts PWM (Pulse-Width-Modulation) control scheme. It accepts input voltage (Vin) from 0.95V to 1.8V, and outputs duty cycle from 0~85%. With two ...

Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 A current source. It profits from the accurate internal voltage reference ...
