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

Very disappointing workmanship. Last time.
Size: X-Large, Color: Lavender, Size: X-Large, Color: Lavender
Shirt came in actually nice day packaged. But opening it up spots all over the shirt very wheat material sending it back back.

High quality polo
Size: 3X-Large, Color: Dark Grey
Can’t beat this price and quality. With mainstream polos is going for about $80. This is a steal for the same quality. Fits good. Price is nice. Keeps me dry the golf course.

Nice Stylish Midweight Jacket
Color: Dark Grey, Size: Medium, Color: Dark Grey, Size: Medium
I ordered this jacket because I wanted something with a little my style to wear out to dressy casual occasions. This jacket fits the bill. It looks nice in that it's got a casual laid back feel but at the same time you could wear over a collared shirt and it would look good.
I am 5'10" and about 165 lbs. I normally wear somewhere between a medium and large depending on the brand. I ordered a medium and it fit well. The arms and body were both the right length, not too short like some other jackets.
The reason I took 1 star off was because this is advertised as a winter puffer jacket and I wouldn't really call it that. It is a mid weight jacket that can get you by in southern winters but anything really cold I wouldn't wear this. Plus it's not a "puffer" jacket. It just has a minimal quilted feel to it but most of it is just a polyester glossy sweatshirt feel.

Maelreg Does It Again
Color: Dark Grey, Size: Medium
I just wrote a review for another Maelreg product. They're all good! lol 21st century fabrics are here to save us! ;) This one is also really well made. I love the fit and feel. It's perfect for those mild fall/spring days where an extra layer of windproof protection is just really handy. The arms aren't insulated, so it's great for active outdoor ventures. I use mine for jogging over a poly/blend wicking tee. It lives at the office where I sometimes need a stylish overcoat in the A/C freezing office. I bought a size M for my 5'10" 175 lb. frame and it fits perfectly. Just long enough to sit at the top of my glutes. The front of the jacket has a nice contrast/sheen that you don't see everywhere, it's a nice style addition. The poly blend fabric adds a nice degree of flex to the fit, it's comfortable under a heavy overcoat or over a light thermal layer. Super easy to launder on cold/low, and really low temp iron to rid it of those packaging wrinkles, and its easy care forever. Great product at a really nice price point, all things considered.
