source, frequency jittering, cycle-by-cycle current limit, and
thermal shutdown circuitry onto a monolithic IC. The start-up
and operating power are derived directly from the DRAIN pin,
eliminating the need for a bias winding and associated circuitry.
The 200 kHz maximum switching frequency allows very
low ?ux transformer designs, practically eliminating audible
noise with the simple ON/OFF control scheme using standard
varnished transformer construction. Ef?cient operation at this
high switching frequency is achieved due to the optimized
switching characteristics and small capacitances of the integrated
power MOSFET. 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. The internal oscillator frequency is
jittered to signi?cantly reduce both the quasi-peak and average
EMI, minimizing ?ltering cost.
