Enhanced Safety and Reliability 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 singlesided
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
Applications
• Supplies for appliances, home building automation, PC standby and
other auxiliary power supplies.
Description
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
