+115C Maximum Case Temperature Features -45C Minimum Case Temperature DC/DC Converter Built-in EMC Filter Ribbed Case Style ICE 2250VDC Isolation Technology* EN-55022 Class B RPP50-2412S Description 50 Watt 2:1 The RPP50 series 2:1 input range DC/DC converters are ideal for high end industrial applications and COTS Military 2 x 1.2 applications where a very wide operating temperature range of -45C to +115C 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 RPP50 is available in a ribbed case style for active cooling. They are UL-60950-1 certified. Ribbed Style Single Output Selection Guide Part Input Input Output Output Efficiency Max.

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 converters 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 converters output pins. Use of the trim and sense function can cause output voltages to increase, thereby increasing output power beyond the converters specified rating.
