Energy Efficient, Offline Switcher with Enhanced Flexibility and Extended Power Range
TNY178PN overview
The TNY178PN is an Energy Efficient, Offline Switcher with Enhanced Flexibility and Extended Power Range made by Power Integrations, supplied in these packages: DIP, SO 8 Pin Type. The absolute maximum ratings table on this page lists the 5 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the TNY178PN pinout and maximum ratings, with the full datasheet PDF to preview below or download.
TinySwitch™-LT incorporates a 650 V power MOSFET, oscillator, high-voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.
Datasheet
TNY178PN features
- Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset
- Auto-restart delivers <3% of maximum power in short-circuit and open loop fault conditions
- Output overvoltage shutdown with optional Zener
- Very low component count enhances reliability and enables single-sided printed circuit board layout
- High bandwidth provides fast turn on with no overshoot and excellent transient load response
- Extended creepage between DRAIN and all other pins improves field
- reliability
