POWER INTEGRATIONS LNK306PN AC/DC Off-Line Switcher IC, Buck-Boost, Flyback, 85 VAC - 265 VAC, 66 kHz, 360 mA output, DIP-8The 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,
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
- 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

Love!
Size: 1.7 Fl Oz (Pack of 1)
It’s a little runny but honestly doesn’t bother me at all. Gives me a good glow with a little coverage! Better than any expensive ones I’ve used & layers well with or without makeup. Just wish it was a higher spf but definitely buying again.

So moisturizing
Color: Rose
I love this lip gloss. It is so moisturizing and such a pretty gloss. I don't find it to be very plumping, but it is very hydrating. I love that it's giving me SPF at the same time. I keep one in my purse, one in my car, and one in my swim bag.
