ELECTRICAL C HARA C TERISTICS
V IN = 15V, V C = 0.5V, V FB = V REF , output pin open, unless otherwise noted.
The q denotes the specifications which apply over the full operating
temperature range, 0 ° C to 100 ° C for the regulator chip and 0 ° C to 125 ° C
for the diode.
Note 1: Measured with V C in hi clamp, V FB = 0.8V. I SW = 1A.
Note 2: For duty cycles (DC) between 50% and 80%, minimum
guaranteed switch current is given by I LIM = 0.833 (2 – DC).
Note 3: Minimum input voltage for isolated flyback mode is 7V.
Note 5: See graphs for guaranteed forward voltage and reverse leakage
current over temperature. Parameters are 100% tested at 25 ° C and
guaranteed at other temperatures by design and QA sampling.
Note 6: Package soldered to FR4 board with ≥ 1oz copper and an internal
or backside plane underneath the package to aid thermal transfer. Diode is
partly thermally coupled to regulator section. See Application Information
section for details on thermal calculations.
Note 4: Because the catch diode has a peak repetitive reverse voltage of
20V, diode breakdown may be the limiting factor on input voltage or
switch voltage in many applications.
