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

Notes:
1. Minimum continuous power in a typical non-ventilated enclosed adapter
measured at 50 °C ambient.
2. Minimum practical continuous power in an open frame design with adequate
heat sinking, measured at 50 °C ambient (See Key Applications
Considerations).

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
signi?cantly reduce both the quasi-peak and average EMI,
minimizing ?ltering cost.
