TOP258PN

The TOP258PN is a highly integrated power switching IC engineered for efficient power conversion in a broad range of electronic applications. It integrates a high-voltage power MOSFET with a PWM controller to simplify circuit design, reduce external component count, and optimize overall system cost and size. 700 V maximum voltage rating for robust operation in high-voltage environments. 0.8 A peak current capability to support demanding power loads with reliable switching. Fixed 60 kHz switching frequency for stable and predictable regulation. Built-in soft-start to limit inrush current and improve reliability. Thermal shutdown to protect the device from overheating. Compared with earlier generations and many discrete alternatives, the TOP258PN’s level of integration reduces board space and simplifies layout while improving thermal performance through optimized switching characteristics. These attributes make it well suited to compact power supplies and designs where component count, efficiency, and thermal management are priorities. Designed for straightforward implementation, the TOP258PN enables designers to achieve precise control and dependable operation across varying load conditions without the need for extensive external circuitry.
