Maximum voltage between HI and SENSE HI = 3V.
Maximum voltage between LO and SENSE LO = 3V.
Voltage output headroom:
40V range:
Max. output voltage = 42V – total voltage drop across source leads (maximum 1

6V range:
Max. output voltage = 8V – total voltage drop across source leads.
Over temperature protection:
Internally sensed temperature overload puts unit in standby mode.
