Typical ADP322 Application Circuit GENERAL DESCRIPTION The ADP322CPZ-REDYKIT™ allows simplified prototyping and evaluation of the ADP322 models. This allows the user to evaluate the voltage options with one easy-to-order kit. 09300-001 All surface-mount ADP322 parts are sorted and stored in the kit with the Analog Devices, Inc., part number and fixed output voltage clearly printed on each zip-top bag. Figure 1. Power Management RedyKit The kit can be used in the engineering lab to evaluate required voltage options. If other voltage options must be evaluated, a different part from the kit can be easily soldered onto one of the evaluation boards supplied with the kit. The ADP322CPZ-REDYKIT is available with a triple, fixed LDO evaluation board and a triple, adjustable LDO evaluation board. The kit also contains additional parts for prototyping. The kit enclosure, which contains individually packaged parts and the two evaluation boards, is packaged in an ESD foam pad inside a treated cardboard box that measures 8.7" (L) × 7.9" (W) × 1.75"(H), that is, 22 cm (L) × 20 cm (W) × 4.5 cm (H). For additional information, see the ADP322 evaluation board user guide (UG-186). PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS.
