Product Highlights
TinySwitch-II Features Reduce System Cost
Fully integrated auto-restart for short circuit and open loop fault
protection – saves external component costs
Built-in circuitry practically eliminates audible noise with ordinary
dip-varnished transformer
Programmable line undervoltage detect feature prevents power
on/off glitches – saves external components
Frequency jittering dramatically reduces EMI (~10 dB)
– minimizes EMI lter component costs
132 kHz operation reduces transformer size – allows use of
EF12.6 or EE13 cores for low cost and small size
Very tight tolerances and negligible temperature variation on key
parameters eases design and lowers cost
Lowest component count switcher solution
Expanded scalable device family for low system cost
Better Cost/Performance over RCC & Linears
Lower system cost than RCC, discrete PWM and other
integrated/hybrid solutions
Cost effective replacement for bulky regulated linears
Simple ON/OFF control – no loop compensation needed
No bias winding – simpler, lower cost transformer
Simple design practically eliminates rework in manufacturing
EcoSmart
– Extremely Energy Efcient
No load consumption <50 mW with bias winding and
<250 mW without bias winding at 265 VAC input
Meets California Energy Commission (CEC), Energy Star, and
EU requirements
Ideal for cell-phone charger and PC standby applications
High Performance at Low Cost
High voltage powered – ideal for charger applications
High bandwidth provides fast turn on with no overshoot
Current limit operation rejects line frequency ripple
Built-in current limit and thermal protection improves safety
Description
TinySwitch-II integrates a 700 V power MOSFET, oscillator, high
voltage switched current source, current limit and thermal
shutdown circuitry onto a monolithic device. The start-up and
operating power are derived directly from the voltage on the
DRAIN pin, eliminating the need for a bias winding and
associated circuitry. In addition, the TinySwitch-II devices
incorporate auto-restart, line undervoltage sense, and frequency
jittering. An innovative design minimizes audio frequency
components in the simple ON/OFF control scheme to practically
eliminate audible noise with standard taped/varnished

transformer construction. The fully integrated auto-restart circuit
safely limits output power during fault conditions such as output
short circuit or open loop, reducing component count and
secondary feedback circuitry cost. An optional line sense resistor
externally programs a line undervoltage threshold, which
eliminates power down glitches caused by the slow discharge of
input storage capacitors present in applications such as standby
supplies. The operating frequency of 132 kHz is jittered to
signicantly reduce both the quasi-peak and average EMI,
minimizing ltering cost.
