●High-Voltage Startup

●Fixed PWM Frequency at 100KHz

●Linearly Decreasing PWM Frequency to 18KHz

●Peak-Current-Mode Control

●Cycle-by-Cycle Current Limiting

●Leading-Edge Blanking (LEB)

●Synchronized Slope Compensation

●Internal Open-Loop Protection (OLP)

●VDDUnder-Voltage Lockout (UVLO)

●VDDOver-Voltage Protection (OVP)

●Constant Power Limit (Full AC Input Range)

●Internal OTP Sensor with Hysteresis

●Applications

●General-purpose switch-mode power supplies and flyback power converters, including:

●SMPS for VCR, SVR, STB, DVD & VCD Player, Printer, Facsimile, & Scanner

●Adapter for Camcorder
