The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C, OUTP = 20V to 80V unless otherwise noted.
Note 2: Referenced with respect to OUTN unless otherwise specified.
Note 3: All conditions for external MOSFET turn on must be met. See
Table 1 and Table 2.
