protection circuitry. Compared to discrete MOSFET and
controller or self oscillating (RCC) switching converter
solutions, a TOPSwitch integrated circuit can reduce total cost,
component count, size, weight and at the same time increase
efficiency and system reliability. The TOP209/210 are intended
for 100/110/230 VAC off-line Power Supply applications in
the 0 to 8 W (0 to 5 W universal) range.
