A simple three-component solution for a switching regulator chip to use for output voltage programming via PWM.

For not using a scope, this method is pretty accurate, and only uses two discrete circuit components (the resistor and the speaker). If you’re ever in a pinch with PWM, this is sure to help ...

Power management leader, Kinetic Technologies, is expanding its portfolio with the introduction of KTB2140. This single-chip, ...

Of course, the standard way of controlling CPU fans these days is with PWM, so he built a circuit which essentially converts the PWM signal from the motherboard into a phantom thermistor.

This design idea revisits another: “PWM power DAC incorporates an LM317.” Like the earlier circuit, this one implements a power DAC by integrating an LM317 positive regulator into a mostly passive PWM ...

This KTB2140 current-mode PWM controller can operate as an active ... Protection features include OCP, short-circuit, thermal, under-voltage lockout (UVLO) and over-voltage protection (OVP).
