This datasheet also covers the TNY280 variant, as both devices belong to the same energy efficient / off-line switcher family and are provided as variant models within a single manufacturer datasheet.
General Description
TinySwitch™-III incorporates a 700 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.
Key Features
Accurate hysteretic thermal shutdown protection with
automatic recovery eliminates need for manual reset.
