The RPP30 series 4:1 input range DC/DC converters are ideal for high end industrial applications and COTS Military
applications where a very wide operating temperature range of -45°C to +115°C is required. Although the case size
is very compact, the converter contains a built-in EMC filter EN-55022 Class B without the need for any external
components. The RPP30 is available in a ribbed case style for active cooling. They are UL-60950-1 certified.

DC/DC Converter
Trimming Output Voltage
Only the single output converters have a trim function that allows users to adjust the output voltage from +10% to -10%, please refer to
the trim table that follow for details. Adjustment to the output voltage can be used with a simple fixed resistor as shown in Figures 1 and 2.
A single fixed resistor can increase or decrease the output voltage depending on its connection. Resistor should be located close to the converter.
If the trim function is not used, leave the trim pin open.
Trim adjustments higher than the specified range can have an adverse effect on the converter´s performance and are not recommended.
Excessive voltage differences between output voltage sense voltage, in conjunction with trim adjustment of the output voltage; can cause
the OVP circuitry to activate. Thermal derating is based on maximum output current and voltage at the converter´s output pins. Use of
the trim and sense function can cause output voltages to increase, thereby increasing output power beyond the converter´s specified rating.
Therefore: (Vout at Pins) X (Iout)
≤
rated output power.

Soldering
Hand Soldering
Hand Soldering is the least preferred method because the amount of
solder applied, the time the soldering iron is held on the joint, the
temperature of the iron and the temperature of the solder joint are
variable.
The recommended hand soldering guideline is listed in Table 1. The
suggested soldering process must keep the power modules internal
temperature below the critical temperature of 217°C continuously.

Wave Soldering
High temperature and long soldering time will result in IMC layer
increasing in thickness and thereby shorten the solder joint lifetime.
Therefore the peak temperature over 245°C is not suggested due
to the potential reliability risk of components under continuous high-
temperature. In the meanwhile, the soldering time of temperature
above 217°C should be less than 90 seconds. Please refer to the sol-
dering profile below for recommended temperature profile parameters.

Notes:
Note3:
To ensure a good all-round electrical contact, the bottom plate is pressed firmly into place into the aluminium case.The hydraulic press can
leave tooling marks and deformations to both the case and plate. The case is anodised aluminium, so there will be natural variations in the case
colour and the aluminium is not scratch resistant. Any resultant marks, scratches and colour varations are cosmetic only and do not affect the
operation or performance of the converters.
