Description

The RP12-AR series DC/DC converters are designed for railway rolling stock applications with an

extra wide continuous input voltage range of 36-160VDC (185VDC for 1s), making them suitable for

48V, 72V, 96V and 110VDC railway systems, but they are also suitable for non-railway high voltage

battery applications. They have a built-in class A ﬁlter network and offer single or dual outputs from

3.3V up to +/-24V. The high efﬁciency permits an ambient temperature range from -40°C to +85°C

without derating, forced cooling or the need for heatsinks. The RP12-AR series feature UVLO, OVP, SCP

and OLP. This makes them ideal for many harsh railway and industrial applications such as powering

IoT sensors, battery management systems or electric fork-lift trucks. The RP12-AR is available in an

industry standard 1” x 1” package and comes with a 3 year warranty.

Model Numbering

Notes:

Note1: Efﬁciency is tested at nominal input and full load at +25°C ambient

Note2: Max. Cap Load is tested at nominal input and full resistive load

Notes:

Note3: add sufﬁx “P” for positive logic (1=ON, 0=OFF)

add sufﬁx “N” instead for negative logic (0=ON, 1=OFF)

or sufﬁx /XC for omitted CTRL pin (refer to dimension drawing)

This is accomplished by connecting an external resistor between the Trim pin and either the +Vout or -Vout pins. With an external resistor between the Trim and -Vout pin, the output voltage increases.
