LNK3604D-TL

LinkSwitch™-XT2 energy efficient, low power off-line switcher IC with integrated system level protection incorporates a 725V power MOSFET, oscillator, simple ON/OFF control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry. No-load consumption is 100mW without bias winding at 265VAC input (10mW with bias winding). Easily meets all global energy efficiency regulations Applications includes flyback converters, supplies for appliances, industrial systems and metering.

• Output power of 9.2W at 230VAC ±15% and 6.1W at 85-265VAC (peak or open frame)
• Easy to design, features superior to linear/RCC, EcoSmart™ extremely energy efficient
• Lowest component count switcher solution, selectable device current limit
• Fully integrated auto-restart for short-circuit and open-loop protection
• Optional self-biased supply, frequency jittering greatly reduces EMI
• Meets HV creepage requirements between DRAIN and all other pins both on the PCB and at the package
• Output overvoltage protection, input overvoltage line and hysteretic overtemperature protection
• Extended creepage between DRAIN pin and all other pins improves field reliability
• Extremely low component count enhances reliability, allows single-sided PCB
• ON/OFF control provides constant efficiency to very light loads
