.fairchildsemi. Features - - - - - - - - - - - - - - Voltage Mode PWM Controller Description The FAN7556 is a fixed frequency voltage mode PWM controller. It is specially designed for off-line and DC-DC converter applications with minimal external ponents. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature pensated reference, an on/off control, a high gain error amplifier, a current sensing parator, and a high current totem-pole output. The FAN7556 has various protection functions such as an over load protection (OLP), an over current protection(OCP), and an over voltage protection(OVP). The FAN7556 is available in...
