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

The ADP1660 may be damaged if the junction temperature

(TJ) limits are exceeded. Monitoring ambient temperature (TA)

does not guarantee that TJ is within the specified temperature

limits. In applications with high power dissipation and poor PCB

thermal resistance, the maximum TA may need to be derated.

In applications with moderate power dissipation and low PCB

thermal resistance, the maximum TA can exceed the maximum

limit as long as TJ is within the specification limits.

The junction temperature (TJ) of the device is dependent on

the ambient temperature (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)

THERMAL RESISTANCE

The junction-to-ambient thermal resistance (θJA) of the package

is based on modeling and calculation using a 4-layer board. θJA

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 environmental conditions. The specified value of θJA is based

on a 4-layer, 4 inch × 3 inch, 2½ oz copper board, per JEDEC

standards. For more information, see the AN-617 Application

Note, Wafer Level Chip Scale Package.

In Table 5, θJA is specified for a device mounted on a JEDEC

2S2P PCB.
