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 fl exible solution with a low system cost and extended power capability.
Applications
Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc. PC Standby and other auxiliary supplies DVD/PVR and other low power set top decoders Supplies for appliances, industrial systems, metering, etc.
Feature
- Simple ON/OFF control, no loop compensation needed
- Self-biased - No bias winding or bias components
- Pin-out simplifies heat-sinking to the PCB
- SOURCE pins are electrically quiet for low EMI
- Output overvoltage shutdown with optional Zener
- Line under-voltage detect threshold set using a single optional resistor
- High bandwidth provides fast turn on with no over-shoot and excellent transient load response
- Extended creepage between DRAIN and all other pins improves field reliability
