TOP246PN

The TOP246PN is a high-performance power integrated circuit engineered for efficient energy conversion in switching power supplies. It combines a 725 V power MOSFET with integrated PWM control and current-mode regulation to deliver stable output control, reduced external component count, and consistent performance across a wide range of applications. Built-in 725 V power MOSFET for high-voltage operation and simplified power stage design. Fixed 65 kHz switching frequency provides predictable EMI behavior and consistent timing for power conversion. Integrated PWM and current-mode control for accurate regulation, fast transient response, and inherent overload protection. Thermal shutdown and overcurrent limiting enhance device and system reliability under adverse conditions. Integration of the power MOSFET and control circuitry in the TOP246PN reduces external parts and simplifies PCB layout, enabling more compact and cost-effective supply designs. Its fixed-frequency operation and current-mode control improve transient response and make loop compensation straightforward for designers targeting stable regulation across varying loads. These combined attributes make the TOP246PN a practical choice for designers seeking a compact, reliable solution for offline and isolated switching power supplies where reduced component count, predictable EMI performance, and built-in protection features are priorities.
