Description
●This highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light-load and zero-load conditions.
●Features
● Linearly Decreasing PWM Frequency
● Green Mode Under Light-Load and Zero-Load Conditions
● Constant Voltage (CV) and Constant Current (CC)
● No Secondary Feedback
● Low Startup Current: 8μA
● Low Operating Current: 3.6mA
● Leading-Edge Blanking
● Constant Power Limit
● Universal AC Input Range
● Synchronized Slope Compensation
● 140°C OTP Sensor with Hysteresis
● VDDOver-Voltage Clamping
● Cycle-by-Cycle Current Limiting
● Under-Voltage Lockout (UVLO)
● Fixed PWM Frequency with Hopping
● Gate Output Maximum Voltage Clamped at 17V
● Small SSOT-6 Package
●Applications
●General-purpose, switching mode, power supplies and flyback power converters, such as:
● Battery Chargers for Cellular Phones, Cordless Phones, PDAs, Digital Cameras, Power Tools
● Power Adapters for Ink Jet Printers, Video Game Consoles, Portable Audio Players
● Open-Frame SMPS for TV/DVD Standby and Auxiliary Supplies, Home Appliances, Consumer
●Electronics
● Replacement for Linear Transformers and RCC SMPS
