Selecting a PWM controller has become less straight forward as leading edge DSPs, FPGAs and CPUs run on increasingly lower supply voltages and consume higher current. Sub 1V voltages are becoming ...

A pulse width modulator (PWM) controller from Microchip Technology allows the introduction of digital control into analog power-supply designs while providing high-speed PWM operation. Designed for ...

Modern power delivery systems with DSPs, FPGAs and CPUs run on lower supply voltages and consume higher current. In fact, sub-1 V voltages are everywhere now. Meanwhile, intermediate bus voltages have ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

The NCP1603 from ON Semiconductor (Phoenix, Ariz.) combines a power-factor correction (PFC) control chip and a pulse-width modulation (PWM) control chip in a single 16-pin SOIC package. This ...

[James] recently finished up a gigantic seven segment display for Nottingham Hackerspace, and although it looks great, the display isn’t the interesting part. The PWM dimmer control implemented in ...

[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...
