The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...

A while back, I published the Design Idea (DI) “Simple PWM interface can program regulators for Vout < Vsense.” It showed some simple circuits for PWM programming of standard bucking-type regulator ...

Intersil’s ISL6277A Multiphase PWM Regulator provides a fully compliant multiphase PWM regulator with AMD Fusion SVI 2.0. This device boosts several other key features. Both outputs support DCR ...

The ISL8500 is a high-performance, 24V, 2A standard buck PWM regulator that provides a simple power system for a variety of point-of-load applications. The PWM controller in the ISL8500 drives an ...

Switch-mode regulators include the buck (step-down) and the boost (step-up), forward and flyback topologies, as well as the SEPIC, hysteretic and multiphase converters. Two basic IC topologies are ...

3.3V to 1.2V high efficiency converter with 50mA driving capability, PWM Regulator, UMC 0.13um HS/FSG Logic process.

Internet of Things (IoT) applications are getting numerous, more power-stringent and smaller with every generation, requiring tighter control of power management and maximized function integration.

Remember the fully integrated voltage regulator (FIVR) introduced with Haswell CPUs? Turns out that news of Intel axing the technology was not completely true. Intel's previous FIVR was implemented to ...
