Product Summary

The fan7554 is a fixed frequency current mode PWM controller. The fan7554 is specially designed for off-line and DC to DC converter applications with minimal external components. The fan7554 features 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 over load protection, an over current protection, and the over voltage protection, which include built-in auto restart circuit. Applications of the fan7554 include: Off-Line & DC-DC Converters.
