Product Overview
The TNY278GN is an energy-efficient, Off-line Switcher IC with enhanced flexibility and extended power range. It incorporates a 700V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. It uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.
- Higher current limit extends peak power or in open frame applications, maximum continuous power
- Lower current limit improves efficiency in enclosed adapters/chargers
- Tight I²f parameter tolerance reduces system cost
- Maximizes MOSFET and magnetic power delivery
- No bias winding or bias components self-biased
- Frequency jittering reduces EMI filter cost
- Pin-out simplifies heat sinking to 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
- Extended creepage between DRAIN and all other pins improves field reliability
