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.

Internal High-Voltage Startup Switch
Burst Mode Operation
Line Voltage Feedforward to Limit Maximum Power
Line Under-Voltage Protection
Latch Protection & Internal Soft-Start (10ms) Function
Overload Protection (OLP)

Description
The FAN7602C is a green current-mode PWM controller.
It is specially designed for off-line adapter applications;
DVDP, VCR, LCD monitor applications; and auxiliary
power supplies.
The internal high-voltage startup switch and the burst
mode operation reduce the power loss in standby mode.
As a result, the input power is lower than 1 W when the
input line voltage is 265 V
AC
and the load is 0.5 W. At
no-load condition, input power is under 0.15 W.
The maximum power can be limited constantly,
regardless of the line voltage change, using the power
limit function.
The switching frequency is not fixed and has random
frequency fluctuation.
The FAN7602C includes various protections for the
system reliability and the internal soft-start prevents the
output voltage over-shoot at startup.
Applications
Adapter
LCD Monitor Power
Auxiliary Power Supply
