HD2-100 Characteristics
Input Voltage............................................................ 36-75 VDC (48V, nominal).
Input Current............................................................ 2.5A, typical at nominal input (Note 1).
EMI Suppression ..................................................... Pi input filter, standard.
Input/Output Isolation.............................................. 1500 VDC, input to output, for one minute.
Continuous Output Power ....................................... Total output power should not exceed 100W.
DC Output................................................................ See Electrical Characteristics table.
Base-Plate Temperature.......................................... +100°C, maximum: Internal thermal shutdown circuitry; automatic
recovery.
Output Voltage Adjustment...................................... Outputs V1 and V2 each adjustable by 5%, minimum.
Short-Circuit Protection ........................................... Continuous cycle-by-cycle current limiting, each output, with auto-
matic recovery
Under-Voltage Protection ........................................ Lockout activated at 34V-35.5V input; automatic recovery with 2V-
3V hysteresis (typical).
Over-Voltage Protection .......................................... 5V output,shutdown at 6.5V, typical; 3.3V output, shutdown at 3.9V,
typical; 2.5V output, shutdown at 3.2V, typical. RESET at VIN = 0V.
Transient Response................................................. 200µs recovery after half-load to full load step change to within 1%
of the regulation band with no more than 5% deviation.
Frequency of Operation........................................... 400 kHz, fixed.
