DC-DC Converter
Application Notes
Input Fusing and Safety Considerations
The QHL750 series converters have no internal fuse. In
order to achieve maximum safety and system
protection, always use an input line fuse. We
recommended a 30 A fast acting fuse. It is also
recommended that the circuit has a transient voltage
suppressor diode (TVS) across the input terminals to
protect the unit against surge or spike voltages and
input reverse voltage (as shown). A suitable part would
be SMCJ78A.
Output Voltage Adjustment
The Trim input permits the user to adjust the output
voltage up by 10% or down by 40%. This is
accomplished by connecting a mandatory external
resistor between the Trim pin and negative sense pin of
value 6.8kOhm. Then select Ru or Rd to determine
desired output voltage.

Example (Without Heatsink)
Remote Control
To determine the minimum airflow necessary for a QHL750300S48 operating at an input voltage of 300 V, an output current of 11A, and a maximum
ambient temperature of 25°C:
Determine Power dissipation (Pd): Pd = Pi-Po = Po(1-η)/η,
Pd = 48V × 11A × (1-0.91) / 0.91 = 47.47
Where Pi = Input power, Po = Output Power and η= Efficiency
Determine airflow from airflow derating graph using data points for Pd = 47.4 W and Ta = 25°C
Minimum airflow= 800 ft./min.
To check that the maximum case temp of 85°C is not exceeded:
Maximum temperature rise is
ΔT = Pd × Rca = 47.47 × 1.23 = 58.38°C.
Maximum case temperature is
Tc = Ta + ΔT = 83.38°C <85°C.
Where: Rca is the thermal resistance from case to ambient environment. Ta is ambient temperature and Tc is case temperature.

Notes
Safety Considerations
The use of a fuse on the input line is recommended for good practice. Additional protection for surges and reverse voltage are also recommended.
Transient voltage suppressors and gas discharge devices can be fitted across the input terminals.
Series & Parallel Configurations
Please contact XP applications engineering for further details.
Ground Connection
The above circuit assumes an earth connection is available. If no earth
present CY capacitors should be connected to case as shown. CY values
might require adjustment depending on the application. Please consult XP
applications engineering for further support.
