TNY254PN,Energy-Efficient Off-Line Switcher,,DIP-8

The TNY254PN-DIP is a part of the TinySwitch series, an innovative solution for low-power offline switching applications. It combines a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal protection circuits into a compact DIP-8 package. The TNY254 offers a cost-effective replacement for bulky linear adapters and RCC-based designs, reducing component count and enhancing energy efficiency.

Operating at a frequency of 44kHz, it delivers high performance while minimizing EMI and video noise in applications like televisions and VCRs. The integrated ON/OFF control ensures rapid response to load changes with minimal output ripple. This switcher eliminates the need for transformer bias windings, simplifying the design and lowering overall cost.

Its universal input capability and advanced thermal management features make it suitable for a variety of power applications, including cellphone chargers, utility meters, and standby power supplies. The TNY254PN-DIP provides robust operation with built-in current and thermal protections, ensuring reliable performance in demanding environments.
