Low power AC-DC SMPS webinar

Solutions for Low power AC-DC SMPS

Meet High Voltage Converter Experts and Optimize Your Next Design

Join us to a 1 hour overview of various offline topologies and how to select the right parts for your specific application, based on topology and features needed. Learn how to design compact sub 20W power supplies using ST’s online design tool, called eDesign Suite. You will also have an opportunity to ask questions to ST’s experienced power supply applications engineers.

Mark your calendars and join us on January 20th at 12 noon CST

12:45 PM – 1:00 PM    Q&A


The VIPerPlus series provides extra ruggedness with its 800V avalanche rated power MOSFETs and offers higher performance with its enhanced energy-saving and noise reduction features.  VIPerPlus offers reliability, efficiency, integration, and versatility with a broad range of features such as quasi-resonant control, jittering, overpower timer, brown-out, etc.

The Altair series has a built-in avalanche-rugged power MOSFET and a PWM controller specifically designed for primary-side regulation (optocoupler-less implementation).  The Altair series is ideal for battery charger applications where regulation of both output voltage and current might be required.

HVLEDs facilitate an efficient, compact and cost-effective solution to drive LEDs directly from the rectified mains. The primary-side regulation cuts bill-of-material costs, while also simplifying design and reducing the space occupied by LED control circuitry.
