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

FAN7601B — Green Current Mode PWM Controller
December 2013
FAN7601B
Green Current Mode PWM Controller
Features
Green Current Mode PWM Control
Low Operating Current: Maximum 4 mA
Burst Mode Operation
Internal High-Voltage Startup Switch
Under-Voltage Lockout (UVLO): 12 V / 8 V
Latch Protection and Soft-Start Function
Over-Voltage Protection: 19 V
Operating Frequency up to 300 kHz
Description
The FAN7601B is a programmable frequency green
current mode PWM controller. It is specially designed for
the offline adapter applications and the auxiliary power
supplies that require high efficiency at light load and no
load. The internal high-voltage startup switch and burst
mode reduce the power loss.
FAN7601B includes protections, such as latch protection
and over-voltage protection. The latch protection can be
used for over-voltage protection, thermal protection, and
others. The soft-start prevents the output voltage
