TNY264PN

The TNY264PN Power Switch IC is an integrated, high-voltage switching solution engineered for compact power-supply designs. Combining a power MOSFET and a PWM controller in a single package, the device reduces component count and PCB area while providing reliable regulation and protection features suitable for low-power applications. Power rating of 0.8 W for efficient energy management in low-power systems. Built-in soft-start capability that limits inrush current and improves start-up reliability. Primary-side control architecture that eliminates the need for an optocoupler and a secondary reference, simplifying designs. Maximum drain-to-source voltage of 700 V to tolerate high-voltage transients. Operating frequency around 132 kHz enabling smaller magnetics and reduced EMI in many designs. By integrating switching and control functions, the TNY264PN streamlines circuit topology compared with discrete component approaches, reducing design complexity and improving reliability. Its high-frequency capability supports smaller transformers and inductors, contributing to lighter, more compact power supplies. The combination of thermal performance and integrated protection features helps maintain stable operation across varying load conditions. These characteristics make the TNY264PN well suited for compact adapters, standby supplies, and other low-power consumer and industrial applications where space, efficiency, and simplified design are priorities.
