Notes:

1) Exceeding these ratings may damage the device.

2) Refer to the Enable (EN) and Configurable UVLO section on

page 17.

3) The maximum allowable power dissipation is a function of the

maximum junction temperature TJ (MAX), the junction-to-

ambient thermal resistance θ

JA, and the ambient temperature

TA. The maximum allowable continuous power dissipation at

any ambient temperature is calculated by PD (MAX) = (TJ

(MAX) - TA) / θJA. Exceeding the maximum allowable power

dissipation can generate an excessive die temperature, which

may cause the regulator to go into thermal shutdown. Internal

thermal

shutdown

circuitry

protects

the

device

from

permanent damage.

4) The device is not guaranteed to function outside of its

operating conditions.

5) Measured on the EVL3435-L-00A, a 4-layer, 2oz PCB

(63mmx63mm).

6)

The value of θ

JA given in this table is only valid for comparison

with other packages and cannot be used for design purposes.

These values were calculated in accordance with JESD51-7,

and simulated on a specified JEDEC board. They do not

represent the performance obtained in an actual application.
