FAN7556規(guī)格書詳情
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 the 8DIP package as well as the 8SOP package.
