STMicroelectronics 20W SMPS Offline Converter DIP8

The STMicroelectronics 20W SMPS Offline Converter is a high-performance fixed frequency offline converter housed in an 8-pin DIP package. It combines a dedicated current mode PWM controller with a high voltage power MOSFET on the same silicon chip, offering an efficient and compact solution for your power management needs.

This advanced converter features an internal control circuit that provides a large input voltage range on the VDD pin, accommodating changes in auxiliary supply voltage. This specific feature makes it particularly well-adapted to battery charger adapter configurations.

With a fixed switching frequency of 60kHz and a wide VDD voltage range of 9V to 38V, this device delivers reliable performance. It supports an input voltage range from 195VAC to 265VAC and boasts a maximum power rating of 20W. Measuring 40 mm x 30 mm x 25 mm and weighing just 0.47 grams, it is ideally suited for space-constrained applications.
