Low duty cycle pulse testing with Kelvin connections required.
Defined as the input to output differential at which the output voltage drops to 1.5% below the value measured at a
differential of 0.5V.
Required to maintain regulation. Voltage set resistors R1 and R2 are usually utilized to meet this requirement.
Guaranteed by design.
When V_FB exceeds this threshold, the “Sense Select” switch disconnects the internal feedback chain from the error
amplifier and connects V_FB instead.
