Low-Cost Green-Mode PWM Controller for Flyback Converters
SG6859A — Low Cost, Green-Mode PWM Controller for Flyback Converters August 2010 SG6859A Low-Cost, Green-Mode PWM Controller for Flyback Converters Features Description This highly integrated PWM controller provides several ƒ Green-Mode PWM enhancements designed to meet the low standby-power ƒ Supports the “Blue Angel” Standard needs of low-power SMPS. To minimize standby power consumption, the proprietary green-mode function ƒ Low Startup Current: 9μA provides off-time modulation to linearly decrease the ƒ Low Operating Current: 3mA switching frequency under light-load conditions. This ƒ 300mA Driving Capability green-mode function enables the power supply to meet even the strictest power conservation requirements. ƒ Leading-Edge Blanking The BiCMOS fabrication process enables reducing the ƒ Constant Output Power Limit startup current to 9μA and the operating current to 3mA. ƒ Universal Input To further improve power conservation, a large startup resistance can be used. Built-in synchronized slope ƒ Built-in Synchronized Slope Compensation compensation ensures the stability of peak current ƒ Current-Mode Operation mode control. Proprietary internal compensation ƒ Cycle-by-cycle Current Limiting provides a constant output power limit over a universal AC input range (90V to 264V ). Pulse-by-pulse current AC AC ƒ Under-Voltage Lockout (UVLO) limiting ensures safe operation during short-circuits. ƒ Programmable PWM Frequency with Frequency To protect the external power MOSFET from damage by Hopping supply over voltage, the SG6859A’s output driver is ƒ V Over-Voltage Protection (Auto Restart) DD clamped at 17V. SG6859A controllers can be used to improve the performance and reduce the production ƒ Gate Output Voltage Clamped at 17V cost of power supplies. The best choice for replacing ƒ Low Cost linear and RCC-mode power adapters, the SG6859A is available in 8-pin DIP and 6-pin SSOT-6 packages. ƒ Few External Components Required ƒ Small SSOT-6 Package Applications General-purpose switching mode power supplies and flyback power converters, such as: ƒ Battery chargers for cellular phones, cordless phones, PDAs, digital cameras, and power tools ƒ Power adapters for ink jet printers, video game consoles, and portable audio players ƒ Open-frame SMPS for TV/DVD standby and auxiliary supplies, home appliances, and consumer electronics ƒ Replacements for linear transformers and RCC SMPS ƒ PC 5V standby power © 2007 SG6859A • Rev. 1.0.4
