Thermal Resistance

θJA

θJC

UTQFN (1.2mmx1.6mm)

Notes:

1) Exceeding these ratings may damage the device.

2) 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 produces an excessive die temperature, causing

the regulator to go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

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

operating conditions.

4) Measured on EV2172C-Q-00A demo board, 2-layer PCB.

5) Measured onJESD51-7, 4-layer PCB.

note 5) 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 are calculated in accordance

with JESD51-7, and simulated on a specified JEDEC board.

They do not represent the performance obtained in an actual

application
