The TNY275GN is a 8.5W energy-efficient Off-Line Switcher IC with enhanced flexibility and extended power range. TinySwitch-III incorporates a 700V power MOSFET, oscillator and high voltage switched current source, current limit and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution and extended power capability.
- Simple ON/OFF control, no loop compensation needed
- Self-biased - No bias winding or bias components
- Pin-out simplifies heat-sinking to the PCB
- SOURCE pins are electrically quiet for low EMI
- Output overvoltage shutdown with optional Zener
- Line under-voltage detect threshold set using a single optional resistor
- High bandwidth provides fast turn on with no over-shoot and excellent transient load response
- Extended creepage between DRAIN and all other pins improves field reliability
