DETAILED DESCRIPTION (continued)

The devices with fixed output voltages are trimmed to operate with an output voltage accuracy of

±3%.

The accuracy of the adjustable version is determined by the accuracy of the internal voltage reference, the

controller topology, and the accuracy of the external resistor. The reference voltage has an accuracy of

±4% over

line, load, and temperature. The controller switches between fixed frequency and pulse-skip mode, depending on

resistors in the feedback divider determine the total system accuracy.
