Accurate hysteretic thermal shutdown protection with
automatic recovery eliminates need for manual reset
• Improved auto-restart delivers <3% of maximum power
in short circuit and open loop fault conditions
• 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 field reliability

• PC Standby and other auxiliary supplies
• DVD/PVR and other low power set top decoders
• Supplies for appliances, industrial systems, metering, etc.
