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 ...

Microchip Technology Inc., has announced the MCP1631 2.0 MHz, high-speed Pulse Width Modulator (PWM). The highly integrated device contains a 1 Ampere (A) integrated MOSFET driver, high-speed ...

If you ever thought of experimenting with pulse-width modulation, this circuit should get you started nicely. We’ve kept simplicity in mind and used a dual 555 timer, making the circuit a piece of ...

Meylan, France – March 25, 2011 --The new PWM audio modulator of Dolphin Integration, sDACS95-SP.01-OL.LB-Titanium, presents numerous high added-value features for advanced fabrication processes: 65 ...

Transient response is a key performance parameter for the multiphase voltage regulator, especially in microprocessor applications. Conventional pulse-width modulation (PWM) schemes have delay times ...
