The FAN7556 is a fixed frequency voltage mode PWM controller. It is designed for off-line and DC-DC converter applications with minimal external components. These ICs feature precise duty cycle control for trimmed oscillators, temperature compensated references, on/off control, high gain error amplifiers, current sense comparators, and high current totem pole outputs. FAN7556 has various protection functions such as Overload Protection (OLP), Over Current Protection (OCP), Over Voltage Protection (OVP). FAN7556 is available in 8DIP package as well as 8SOP package.
