Design Rugged Power Supplies with NCP1252ADR2G: A High-PerformanceCurrent-Mode PWM Controller

Design rugged power supplies with the NCP1252ADR2G, a high-performance current-mode PWM controller designed for forwarding and flyback applications. Developed specifically for the ATX and adapter market, this controller offers a flexible switching frequency and the ability to handle temporary overload/current and latch permanent faults. Plus, the soft-start duration is flexible, enabling smoother power supply operation even after a brownout detection.

Noise immunity is improved, and EMI signature is spread for optimal performance. With no external power MOSFET driver needed, external components and dummy load are saved, and PCB area is conserved.
