com FAN7556 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 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 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 th...
