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.

Output Adjustment

1. Use of an external input line fuse is recommended: Use a 10A/125V slow-blow fuse.

2. For uncompromised operation, the base-plate temperature of HD1-300 must be kept below the maximum of +100°C.

Good engineering practice in observation of that limit, including use of auxiliary heat sinks or forced air cooling, is

entirely the responsibility of the user.

3. All measurements are at nominal input, full load, and +25°C, unless otherwise specified

4. Ripple and noise figures are maximum values. See application note below.

5. Peak-to-peak and RMS metering equipment must have a 20 MHz frequency response with probes and cables that

maintain a frequency response of 20 Hz to 20 MHz. Output ripple and spikes are measured directly at the output

terminals of the converter with a 0.1 µF ceramic capacitor. The probe ground band must make direct contact with

the output return or the common terminal of the converter to prevent noise measurement errors.

In applications with loads between two and three inches from the

HD1-300 module, the circuit board’s trace inductance can be used in

conjunction with a 47 µF, low-ESR capacitor across each load to

lower ripple and noise to 50 mVpp.
