Recommended Operating Conditions

(3)

Supply voltage (VIN).......................... 8V to 32V

Output current (IA,BOUT) .................................±2A

Operating junction temp. (TJ). .. -40°C to +125°C

Thermal Resistance

(4)

θJA

θJC

QFN-28 (4mmx5mm) ............ 40........ 9 .... °C/W

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 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 produces an excessive die temperature, causing

and 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 JESD51-7, 4-layer PCB.
