Description

STR-G6153 is Flyback Converter Switching Regulator for Laser Printer.

An offline quasi-resonant flyback switching regulator is a type of power supply circuit used in offline applications, where the power source is directly connected to the mains voltage (AC line). The term “quasi-resonant” refers to the operating mode of the flyback converter, which combines characteristics of both continuous and discontinuous conduction modes to improve efficiency and reduce switching losses.

The flyback switching regulator is a popular topology for offline power supplies due to its simplicity, cost-effectiveness, and ability to provide galvanic isolation between the input and output. It is commonly used in various low to medium power applications, such as power adapters, LED drivers, and some battery chargers.
