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

Features:

• Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset
• Improved auto-restart delivers <3>
• Output overvoltage shutdown with optional Zener
• Line under voltage detect threshold set using a single optional resistor
• 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 fi eld reliability

Package: PDIP-7
