FAN7554 Datasheet PDF - ON Semiconductor

●The FAN7554 is a fixed frequency current-mode PWM controller. It is specially designed for off-line and DC-to-DC converter applications with minimal external components. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, an ON/OFF control, a high gain error amplifier, a current sensing comparator, and a high current totem-pole output. The FAN7554 has various protection functions such as an overload protection, an over current protection, and the over voltage protection, which includes built-in auto restart circuit. The FAN7554 is available in the 8-DIP package as well as the 8-SOP package.
