TNY266PN - Off Line Switcher - Power Integrations - DIP-8

• Fully integrated auto-restart for short circuit and open loop fault protection
• Built in circuitry practically eliminates audible noise with ordinary dip-varnished transformer
• Programmable line under voltage detect feature prevents power on/off glitches
• Frequency jittering dramatically reduces EMI (~10dB)
• 132kHz operation reduces transformer size
• Very tight tolerances and negligible temperature variation on key parameters
• Low component count switcher solution
• Simple ON/OFF control - no loop compensation needed
• No bias winding
• Simple design practically eliminates rework in manufacturing
• No load consumption <50mW with bias winding and <250mW without bias winding at 265VAC input
• High bandwidth provides fast turn on with no overshoot
• Current limit operation rejects line frequency ripple
• Built in current limit and thermal protection improves safety
