[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 ...

A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...

Any boost-converter design will have a practical limit to how much it can step up a voltage from input to output. Pulse-width modulation (PWM) controllers have timing limits that restrict the minimum ...

away from it. If necessary, adjust airflow by using a voltage-controlled variable speed fan. Thermal performance of the PWM ICs starts with using a standard evaluation board. This board can be ...

One solution to these problems is to smooth the PWM signal with a low-pass filter and use that voltage to control a linear driver. For a 12-V fan, the resulting control voltage is typically 5 V to ...

Available in a 5 x 6mm QFN package with a 4.5 to 40V input voltage range, the device features an internal PWM dimming generator that delivers dimming ratios up to ... It incorporates a high side ...
