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 under-
voltage 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
under-voltage 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 significantly reduce both the quasi-peak
and average EMI, minimizing filtering cost.
