(1)

The JEDEC Low K (1s) board design used to derive this data was a 3-inch x 3-inch, two layer board with 2-ounce copper traces on top

of the board.

(2)

The JEDEC High K (2s2p) board design used to derive this data was a 3-inch x 3-inch, multilayer board with 1-ounce internal power and

ground planes and 2-ounce copper traces on top and bottom of the board.

(1)

To calculate the minimum input voltage for your maximum output current, use the following formula:

XXXX VI(min) = VO(max) + VDO(max load).

(2)

Continuous output current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that

the device operate under conditions beyond those specified in this table for extended periods of time.
