Available from multiple sources, the UC384X family of current-mode, PWM (pulse-width-modulated) power-supply controllers offers good performance and has spawned a variety of similar ICs. All members ...

I recently published a Design Idea (DI) showing some very simple circuits for PWM programming of standard regulator chips, both linear and switching, “Revisited: Three discretes suffice to interface ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

Wonderland’s current pwm to voltage converter mini-project is to interface a modern grblHAL cnc board with a late 1990s era thyristor-based motor control board in an milling machine. The board appears ...

Back in October I was pondering the creation of accurate micro-voltages from a microcontroller. What makes this so difficult is the voltage offset created by current in the microcontroller bond wire, ...
