We see from your search that you're looking for information on the term "PWM controllers",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release PWM controllers suit general applications from
STMicroelectronics, which we summarised at the time by saying "STMicroelectronics' pulse width modulation controllers allow a significant reduction in the cost and size of the power supply".
Several months prior to that,
we featured the news release Dual-edge PWM controllers are dynamic performers from
ON Semiconductor: "Multiphase buck controllers address power needs for servers and for VR10.x, VR11.0 and parallel VID based desktop personal computers".
In February 2007, we covered the news from Maxim Integrated Products
concerning its MAX16819/MAX16820, high-efficiency LED drivers
- take a look at MAX16819/MAX16820, high-efficiency LED drivers
which says: "Maxim Integrated Products introduces the MAX16819/MAX16820, high-efficiency LED drivers for architectural, industrial, and automotive lighting applications".
Take a look also at the news release from Fairchild Semiconductor, Fairchild to acquire balance of System General,
as well as PWM controllers take more discretes onboard from Intersil,
and PWM controllers power dual-core mobile designs from Semtech.
