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 ISL6446A integrates complete control, monitoring and protection functions for two synchronous buck PWM controllers and one linear controller. It allows designers to easily convert 4.5V to 24V DC ...

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 ...

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 ...
