NOTES:

Exceeding these ratings may damage the device.

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 on

EV8770-Q-00A board 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.

The device is not guaranteed to function outside of its operating

conditions.

Measured on JESD51-7, 4-layer PCB.
