HD1-300 Characteristics

Input Voltage............................................................ 36-75 VDC (48V, nominal).

EMI Suppression ..................................................... Pi input filter, standard.

Isolation Voltage ...................................................... 1500V, input to output, for one minute.

Continuous Output Power ....................................... Total output power should not exceed 200W for model HD1-300-3D

or 300W for model HD1-300-5D.

DC Output................................................................ See Electrical Characteristics table.

Base-Plate Temperature.......................................... +100°C, maximum (Note 2): Thermal shutdown circuitry with auto-

matic recovery.

Output Voltage Adjustment...................................... Adjustable by 10%.

Short-Circuit Protection ........................................... Continuous cycle-by-cycle current limiting with automatic recovery.

Under-Voltage Protection ........................................ Lockout activated at 34V-35.5V input; automatic recovery with 2V-

3V hysteresis (typical).

Over-Voltage Protection .......................................... HD1-300-3D, shutdown at 3.9V, typical; HD1-300-5D, shutdown at

6.5V, 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.

Design Topology...................................................... Forward converter.

Remote Shutdown................................................... CMOS and open-collector TTL compatible. Choice of active high or

active low ENABLE: See following table for control conditions.

Power Good Signal ................................................. TTL HIGH = VOUT within tolerance.

Operating Temperature Range................................ -40°C to +100°C (base plate).

Temperature Coefficient .......................................... 0.02%/°C over the operating temperature range.

Relative Humidity .................................................... 0% to 95%, non-condensing.
