Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

THERMAL DATA

Absolute maximum ratings apply individually only, not in

combination.

The ADP5022 can be damaged when the junction temperature

limits are exceeded. Monitoring ambient temperature (TA) does

not guarantee that the junction temperature (TJ) is within the

specified temperature limits. In applications with high power

dissipation and poor thermal resistance, the maximum ambient

temperature may have to be derated. In applications with

moderate power dissipation and low PCB thermal resistance,

the maximum ambient temperature may exceed the maximum

limit as long as the junction temperature is within specification

limits. TJ of the device is dependent on TA, the power

dissipation (PD) of the device, and the junction-to-ambient

thermal resistance (θJA) of the package. Maximum TJ is

calculated from TA and PD using the following formula:

TJ = TA + (PD × θJA)

θJA of the package is based on modeling and calculation using a

4-layer board. The junction-to-ambient thermal resistance is

highly dependent on the application and board layout. In

applications where high maximum power dissipation exists,

close attention to thermal board design is required. The value

of θJA may vary, depending on PCB material, layout, and envi-

ronmental conditions. The specified values of θJA are based on a

4-layer, 4” × 3” circuit board. Refer to JEDEC JESD 51-9 for

detailed information on the board construction. For additional

information, see the AN-617 Application Note, MicroCSPTM

Wafer Level Chip Scale Package.

THERMAL RESISTANCE

θJA is specified for the worst-case conditions, that is, a device

soldered on a circuit board.
