Description

POWER INTEGRATIONS TNY266PN Power Management IC, Low Power Off Line Switcher, 265 VAC, DIP-8The TNY266PN integrates a 700V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry onto a monolithic device. The start up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias winding and associated circuitry. In addition, the TNY266PN incorporates auto restart, line undervoltage sense, and frequency jittering. An innovative design minimises

The TNY266PN integrates a 700V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry onto a monolithic device. The start up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias winding and associated circuitry. In addition, the TNY266PN incorporates auto-restart, line undervoltage sense, and frequency jittering. An innovative design minimises audio frequency components in the simple ON/OFF control scheme to practically eliminate audible noise with standard taped/varnished transformer construction. The fully integrated auto-restart circuit safely limits output power during fault conditions such as output short circuit or open loop, reducing component count and secondary feedback circuitry cost.
  • Fully integrated auto-restart for short circuit and open loop fault protection
  • Built in circuitry practically eliminates audible noise with ordinary dip-varnished transformer
  • Programmable line under voltage detect feature prevents power on/off glitches
  • Frequency jittering dramatically reduces EMI (~10dB)
  • 132kHz operation reduces transformer size
  • Very tight tolerances and negligible temperature variation on key parameters
  • Low component count switcher solution
  • Simple ON/OFF control - no loop compensation needed
  • No bias winding
  • Simple design practically eliminates rework in manufacturing
  • No load consumption <50mW with bias winding and <250mW without bias winding at 265VAC input
  • High bandwidth provides fast turn on with no overshoot
  • Current limit operation rejects line frequency ripple
  • Built in current limit and thermal protection improves safety

No spatulas ?
Size: Tub 8 Ounce
Seems ok so far. We will see. A little disappointed that it didn’t come with the spatulas everyone pictured in the reviews.

easy to use spatula
This two pack of baby spatulas are easy to use and easy to clean. You don't have to worry about getting your fingers sticky or messy when applying creams to your baby. The suction cup on the end is a nice touch so that you can stand these up straight and not get another surface dirty or sticky. Definitely recommend this item to new parents!

Soap bar tumeric
This was the best soap ever. Did not turn my skin orange, (which I was little afraid of) and left it feeling nourished. Used in the shower as a body soap and can't recommend it enough.

I loved it
The texture is amazing, too expensive for its size and it doesn’t last.
