Notes:

1) Exceeding these ratings may damage the device.

2) When the PG pin is pulled up to the power source, the current

should be limited to be below the maximum value.

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

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

ambient

thermal

resistance,

θJA,

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 cause excessive die

temperature, and the converter may 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 EVL2338-TL-00A, 2-layer, 63.5mmx63.5mm

PCB.

6) The value of θJA 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.
