Notes:

() Low duty cycle pulse testing with Kelvin connections required.

(2) Defined as the input to output differential at which the output voltage drops to % below the value measured at a differential of 0.95V for 2.2V ≤ V

at adjustable mode configuration. Not measurable on outputs less than 2.2V due to minimum V

(3) Defined as the output current at which the output voltage drops to 2% below the value measured at output current of 0mA.

(4) Guaranteed by design.
