Unless specified: V
EN = VIN, VFB = VO, VIN = 1.40V to 5.5V, VIN = (VO + 0.5V) to 5.5V and IO = 1mA to 1A.
Values in bold apply over the full operating temperature range.
Notes:
(1)
Low duty cycle pulse testing with Kelvin connections required.
(2)
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.
(3)
Required to maintain regulation. Voltage set resistors R1 and R2 are usually utilized to meet this requirement.
(4)
Guaranteed by design.
(5)
When V
FB exceeds this threshold, the “Sense Select” switch disconnects the internal feedback chain from the error
amplifier and connects V
FB instead.
