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
load current. This adds an offset to the output voltage that is equivalent to 1% of V
O
. The tolerance of the
resistors in the feedback divider determine the total system accuracy.
