EcoSmart – Extremely Energy Ef ?cient
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
?eld reliability
?
? Easily meets all global energy ef?ciency regulations
? No-load <150 mW at 265 VAC without bias winding, <50 mW
with bias winding
? ON/OFF control provides constant ef?ciency down to very light
loads – ideal for mandatory CEC regulations and 1 W PC
standby requirements
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.

Notes:
1. Minimum continuous power in a typical non-ventilated enclosed adapter
measured at +50 °C ambient. Use of an external heatsink will increase power
capability.
2. Minimum peak power capability in any design or minimum continuous power in
an open frame design (see Key Applications Considerations).
3. Packages: P: DIP-8C, G: SMD-8C. See Part Ordering Information.
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 ?exible solution with
a low system cost and extended power capability.
