NOTES:

1) Absolute maximum ratings are rated under room temperature

unless otherwise noted. Exceeding these ratings may

damage the device.

2) For details on EN/SYNC

’s ABS max rating, please refer to the

Enable/SYNC Control section on page 12.

3) 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

the regulator to go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

4) Measured on JESD51-7, 4-layer PCB.
