Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

Description
The FAN7554 is a fixed frequency current mode PWM
controller. It is specially designed for off-line and DC to
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
FAN7554 has various protection functions such as an
overload protection, an over-current protection, and the
over-voltage protection, which include built-in auto
restart circuit. The FAN7554 is available in the 8-DIP
