In this post I will try to gain some insight into the electronics of a cheap PWM Power MOSFET Module. The module under the spotlight is the pretty common FR120N MOSFET Control Module which is a simple ...

The STR4A100 is a series of off-line PWM controllers with integrated sensing MOSFET intended for switching power supplies. These devices feature an automatic standby function with no load power ...

Designers can meet and even exceed standby-power specifications of the U.S. Energy Star standard and the German Blue Angel Eco Norm thanks to a power MOSFET/pulse-width modulation (PWM) controller ...

To drive a MOSFET requires more than merely a logic level output, there’s a requirement to charge the device’s gate which necessitates a suitable buffer amplifier. A variety of different approaches ...

New full-bridge pulse-width-modulation (PWM) controllers developed by National Semiconductor Corp. incorporate all four primary-side bridge MOSFET gate drivers. The LM5045 and LM5046 are the latest ...

Optimised performance, efficiency, and reliability in high-voltage power supplies need to be combined with reduced BOM count and cost, as well as lower design efforts. The FF CoolSET solution combines ...

SCR speed controllers that supply 180Vdc motors from 240Vac mains are wonderfully robust, but have the drawback that they always present fast-rising voltage edges to the motor’s armature at a 100Hz ...

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.
