description (continued)
absolute maximum ratings over operating free-air temperature (unless otherwise noted)
† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
−40°C to 85°C
functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: (1) Specified θja (junction to ambient) is for devices mounted to 5-inch 2 FR4 PC board with one ounce copper
UCC2817 offers an on-chip shunt regulator with low start-up current, suitable for applications utilizing a
bootstrap supply. UCC2818 is intended for applications with a fixed supply (VCC).
Available in the 16-pin D, DW, N and PW packages.
