TNY253P

The TNY253P is a compact, high-performance power conversion module designed for reliable switching power supply applications. It integrates a high-voltage avalanche-rated power MOSFET and a precision controller into a single DIP-7 package, reducing component count and simplifying assembly while improving overall system reliability. 700 V avalanche-rated power MOSFET provides robust tolerance to high-voltage stress and surge events. 0.45 W typical standby power consumption lowers energy waste in idle conditions and contributes to compliant low-power designs. Fixed 132 kHz oscillator ensures stable switching frequency for consistent output regulation. Built-in current limiting circuitry protects against overload and short-circuit conditions to safeguard the supply and load. Compact DIP-7 package enables space-efficient PCB layouts for compact or densely populated designs. Compared with earlier models and many industry equivalents, the TNY253P delivers improved efficiency and thermal performance through its integrated architecture. The combination of a rugged high-voltage MOSFET and an accurate fixed-frequency oscillator provides smooth power delivery and predictable behavior across a range of low-power adapters, standby supplies, and auxiliary power applications. Built-in protection features reduce the risk of damage during abnormal conditions and help extend the operational life of connected devices. The module’s small footprint and integration reduce external component requirements, simplifying design and manufacturing without sacrificing performance.
