Power Integrations, AC-DC Converter, Minimum of 50 V dc 7-Pin, DIP TNY289PG

TinySwitch-4 series Offline AC-DC Converters. A range of energy-efficient, off-line AC-DC converters from Power Integrations. The TinySwitch-4 series combine a high voltage power MOSFET and ON/OFF flyback power supply controller in a single compact package. These devices have excellent no-load and light-load efficiency and extremely fast transient response and are available in both through-hole and SMT options. Line compensated overload power reduces maximum overload variation over input voltage range Simple ON/OFF control, no loop compensation needed Selectable current limit through BP/M capacitor value Self-biased: no bias winding or bias components Frequency jittering reduces EMI filter costs Pin-out simplifies heat sinking to the PCB Accurate hysteretic thermal shutdown protection with automatic recovery Auto-restart delivers ;3% of maximum power in short-circuit and open-loop fault conditions Extended creepage between MOSFET drain and all other pins Easily meets all global energy efficiency regulations No-load ;30 mW with bias winding, ;150 mW at 265 VAC without bias winding
