TNY277PN Datasheet PDF - Power Integrations

●The TNY277PN is a 13W 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
