The LNK306PN is a LinkSwitch-TN lowest component count, energy-efficient off-line Switcher, specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360mA output current range at equal system cost while offering much higher performance and energy efficiency. LinkSwitch-TN devices integrate a 700V 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 voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or flyback converters. The fully integrated auto-restart circuit in the LNK304-306 safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost.

• Lowest Component Count Buck Converter Solution
• Fully integrated Auto-restart for Short-circuit and open loop fault protection saves component costs
• 66kHz Operation with accurate current limit, allows low cost Off-the-shelf 1mH Inductor
• Tight Tolerances and Negligible Temperature Variation
• High Breakdown Voltage of 700V Provides Excellent Input Surge Withstand
• Frequency Jittering Dramatically Reduces EMI (~10dB)
• High Thermal Shutdown Temperature (+135°C Minimum)
• Much Higher Performance Over Discrete Buck and Passive Solutions
• Supports Buck, Buck-boost and Flyback Topologies
• System Level Thermal Overload, Output Short-circuit and Open Control Loop Protection
• Excellent Line and Load Regulation Even with Typical Configuration
