POWER MANAGEMENT

Absolute Maximum Ratings

All voltages with respect to GND. Positive currents are into, and negative currents are out of the specified terminal. Pulsed

is defined as a less than 10% duty cycle with a maximum duration of 500ns. Consult Packaging Section of Data sheet for

thermal limitations and considerations of packages.

Exceeding the specifications below may result in permanent damage to the device, or device malfunction. Operation outside of the parameters specified in

the Electrical Characteristics section is not implied.

Note:

(1). ThetaJA is calculated from a package in still air, mounted to a 3” x 4.5”, 4 layer FR4PCB with thermal vias (if applicable)

per JESD51 standards.
