PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

Intersil Corporation introduced the ZL8801, a dual-phase, DC/DC digital PWM controller. This device is an expansion of Intersil’s fourth generation controller family, which enables a simple 2-phase ...

Interesting question. Before we could really answer it, we had to read up on pulse width modulation and why virtually all of the OEs now use PWM to control their fuel systems. To be clear, we will ...

Intersil has announced the ISL6539, a dual PWM controller IC with built-in protection and monitoring in a single IC. The controller accepts an input voltage from 5V to 15V and can operate from a 3.3 ...

The TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...
