Fuji Electric FA5553
the FA5553 / 5547 series of 8-pin current mode PWM (pulse width modulation) control power supply ICs which feature enhanced low standby power performance and added protection functions suitable for various products. This IC series is used as a PWM IC on the primary side in the conceptual diagram of a switching mode power supply shown in Fig. With the FA5553 series, an external latch type overheat protection function is configured by a thermistor only, enabling the number of external components to be reduced by two components compared to the conventional series.| Part No. | FA5553 |

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, Fuji Electric has developed An overview of this new product series is presented below.
