POWER INTEGRATIONS LNK305PN IC, OFF LINE SWITCHER, 175MA, 280MAThe LNK305PN 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,
The LNK305PN 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
- High Bandwidth Provides Fast Turn-on with No Overshoot
- Current Limit Operation Rejects Line Ripple
- Universal Input Voltage Range (85 to 265VAC)
- Built-in Current Limit and Hysteretic Thermal Protection
- Higher Efficiency than Passive Solutions
- Higher Power Factor than Capacitor-fed Solutions
- Entirely Manufacturable in SMD
- EcoSmart� - Extremely Energy Efficient
- Consumes typically 50/80mW in self-powered buck topology at 115/230VAC input with no-load
Applications
Consumer Electronics, Clock & Timing, LED Lighting, Industrial, Automation & Process Control

I am biased here because I love this author.
Dr. Caputti is very detailed in her information while dispersing it in an organized and easy to follow manner. I would recommend anything she publishes as well any conferences at which she speaks to inform RN/PNs of test strategies and how professionals think through patient scenarios.
