Low Standby Power Under 30mW
High Voltage Startup
Fewest External Component Counts
Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry
Green-Mode Function: Linearly-Decreasing PWM Frequency
Fixed PWM Frequency at 50kHz with Frequency Hopping to Solve EMI Problem
Cable Compensation in CV Mode
Peak-Current-Mode Control in CV Mode
Cycle-by-Cycle Current Limiting
VDD Over-Voltage Protection with Auto Restart
VDD Under-Voltage Lockout (UVLO)
Gate Output Maximum Voltage Clamped at 15V
Fixed Over-Temperature Protection with Auto Restart
Available in the 8-Lead SOP Package
Applications
Battery chargers for cellular phones, cordless phones, PDA, digital cameras, power tools, etc.
