TinySwitch-4 series Offline AC-DC ConvertersA 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 windingAC-DC Converters, Power Integrations
