ONSEMI NCP1207BDR2G PWM Controller
The NCP1207BDR2G is a high-performance PWM current-mode controller designed for free running quasi-resonant operation in switch-mode power supplies. It integrates true current modulation, demagnetization detection, and dynamic self-supply features, eliminating the need for an auxiliary winding. The device ensures border-line conduction mode, minimal drain voltage switching, and adjustable skip cycle functionality for noise-free operation. It offers latched overvoltage protection, overcurrent protection, and internal soft-start, making it ideal for AC/DC adapters, battery chargers, and consumer electronics. Its high-voltage technology simplifies transformer design and enhances reliability.
