Description
This highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. The proprietary topology enables most simplified circuit design especially for battery charger applications. A low-cost, smaller, and lighter charger results when compared to a conventional design or a linear transformer. The startup current is only 10μA, which allows large startup resistance for further power saving.

Features
● Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry
● Green-Mode Function: PWM Frequency Linearly Decreasing
● Fixed PWM Frequency at 50kHz with Frequency Hopping to Solve EMI Problems
● Cable Compensation in CV mode
● Low Startup Current: 10μA
● Low Operating Current: 3.5mA
● Peak-Current-Mode Control in CV Mode
● Cycle-by-Cycle Current Limiting
● VDD Over-Voltage Protection (OVP) with Auto-Restart
● VDD Under-Voltage Lockout (UVLO)
● Fixed Over-Temperature Protection (OTP) with Latch
● DIP-8 Package Available

Applications
● Battery Chargers for Cellular Phones, Cordless Phones, PDA, Digital Cameras, Power Tools
● Best Choice to Replace Linear Transformer and RCC SMPS
