PARAMETER TEST CONDITIONS MIN TYP MAX UNIT (3) For this test, the FA/SYNC/SD Pin is pulled to 3 V using a 40-k? resistor. (4) The overvoltage protection is specified with respect to the feedback voltage. This is because the overvoltage protection tracks the feedback voltage. The overvoltage threshold can be calculated by adding the feedback voltage (VFB) to the overvoltage protection specification. (5) The FA/SYNC/SD pin should be pulled to VIN through a resistor to turn the regulator off. The voltage on the FA/SYNC/SD pin must be above the max limit for the Output = High longer than 30 μs to keep the regulator off and must b
