TNY278PN,Energy-Efficient Off-Line Switcher,16W,DIP-8

The TNY278PN - DIP-8 is a high-efficiency off-line switcher, part of the TinySwitch-III family from Power Integrations, designed for low-power, energy-efficient power supplies. This IC integrates a 700V power MOSFET, oscillator, and current limit state machine into a compact DIP-8 package, providing a cost-effective and flexible solution for designers. With its wide input voltage range and selectable current limit feature, the TNY278PN offers optimized performance in both adapter and open-frame power supply designs.

This switcher delivers up to 16W in adapter designs and up to 28W in open-frame designs at 230VAC, making it ideal for chargers, adapters, DVD/PVR systems, and appliance power supplies. It also features integrated thermal shutdown, auto-restart, and undervoltage protection for enhanced reliability. The frequency jittering capability reduces EMI, minimizing external filtering requirements, while its energy-efficient design helps meet global energy regulations.

With its ON/OFF control scheme, the TNY278PN simplifies power supply design by eliminating the need for loop compensation. The integrated MOSFET and advanced control logic maximize power delivery, making this IC an excellent choice for energy-efficient, low-component count power supply designs.
