1 / 11 page  February 2009 © 2008 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN7601B • Rev. 1.0.1 FAN7601B Green Current Mode PWM Controller Features Green Current Mode PWM Control Low Operating Current: Maximum 4mA Burst Mode Operation Internal High-Voltage Startup Switch Under-Voltage Lockout (UVLO): 12V/8V Latch Protection and Soft-Start Function Over-Voltage Protection: 19V Operating Frequency up to 300kHz Maximum Duty Cycle: 95% Applications Offline Adapter Applications Auxiliary Power Supplies Related Resources AN4129 — Green Current Mode PWM Controller FAN7601 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 overshoot at startup.
