Fuji Electric FA5547
the FA5547 series, in addition to the abovementioned overheat protection, a current limiting function that operates in response to a pulsed load current and is required in power supply units having a load such as a motor, and a brown-out function are built into the IC, enabling the number of external components to be reduced by eight components compared to the conventional series and a reduction in cost of the power supply unit. Meanwhile, in terms of protection functions, a low AC input voltage protection (brown-out) function has been added to the FA5547 series.| Part No. | FA5547 |

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. In response to these requests, Fuji Electric has already developed a series of control ICs for use in switching mode power supply units to convert commercial AC power (100 V or 240 V) to a DC power supply. Recently,...
