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 ...

The trend is clear: The Power Supply industry is starting to accept full-digital control of Switch Mode Power Supplies (SMPS) as a viable control technology. The advantages this trend brings are ...

[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 ...

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 ...

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 ...

[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 ...

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 ...

Precise configuration is simple with a convenient USB connection to a PC. Other features include an operating temperature range of -40 to 80 °C (32-176 ºF), electrical noise immunity, and surge ...

Edit 25/10/19: at 11:15 onwards, Luke discusses the motherboard vrm and power delivery. He has clarified further whether this ...
