SG6860  
Low-Cost, Green-Mode PWM Controller for  
Flyback Converters  
Features  
Description  
This highly integrated PWM controller provides several  
enhancements designed to meet the low standby-power  
needs of low-power SMPS. To minimize standby power

Green-Mode PWM  
Supports the “Blue Angel” Eco Standard  
Low Start-up Current: 9µA  
consumption,  
a
proprietary green-mode function  
Low Operating Current: 3mA  
Leading-Edge Blanking  
provides off-time modulation to linearly decrease the  
switching frequency under light-load conditions. This  
green-mode function enables the power supply to meet  
even strict power conservation requirements.  
Constant Output Power Limit  
Universal Input  
The BiCMOS fabrication process enables reducing the  
start-up current to 9µA and the operating current to  
3mA. To further improve power conservation, a large  
start-up resistance can be used. Built-in synchronized  
slope compensation ensures the stability of peak  
current mode control. Proprietary internal compensation  
provides a constant output power limit over a universal  
AC input range (90VAC to 264VAC). Pulse-by-pulse  
current limiting ensures safe operation even during  
short-circuits.

VDD Over-Voltage Protection (Latch off)  
Gate Output Voltage Clamped at 17V  
Low Cost  
To protect the external power MOSFET from being  
damaged by supply over voltage, the SG6860’s output  
driver is clamped at 17V. SG6860 controllers can  
improve the performance and reduce the production  
cost of power supplies. The SG6860 can replace linear  
and RCC-mode power adapters. It is available in 8-pin  
DIP and 6-pin SOT-26 packages.
