Recommended Operating Conditions

(3)

Supply voltage (VIN)........................ 18V to 24V

Maximum junction temp. (TJ) ................... 125°C

Thermal Resistance

(4)

θJA

θJC

QFN-16 (4mmx4mm) ............ 46....... 10 ... °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

calculated

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 JESD51-7 4-layer board.
