FA5553/5547 Series of PWM Control Power Supply ICs with Multi-functionality and Low Standby Power
Masanari Fujii Hiroshi Maruyama Kokou Boku
1. Introduction
In recent years, global environmental warming has come to be addressed as a worldwide problem and energy savings has become critical for all electric products. In particular, televisions, audio components, notebook computers, printers and other such peripheral devices that are often continuously plugged into an electrical outlet remain in their standby state for a longer duration of time than their actual time of usage, and therefore functions for reducing the power consumption during standby have become essential. Requests for lower standby power consumption in power supply units have also intensified year after year.
