Description
The xRP2-50E2A0 is a non-isolated dc/dc converter that operates over a wide range of input voltage (Vin = 5
Vdc - 13.8 Vdc). This unit can provide a precisely regulated output voltage from 0.6 Vdc to 5.0 Vdc and can
deliver up to 50 A of output current. This unit is designed to be highly efficient and low cost. The converter is
provided in an industry standard package.

Remote Sense
This module has remote sense compensation feature. It can minimize the effects of resistance between
module’s output and load in system layout and facilitates accurate voltage regulation at load terminals or
other selected point.
1. The remote sense lines carries very little current and hence do not require a large cross-sectional area.
2. This module compensates for a maximum drop of 10% of the nominal output voltage.
3. If the unit is already trimmed up, the available remote sense compensation range should be
correspondingly reduced. The total voltage increased by trim and remote sense should not exceed 10%
of the nominal output voltage.
4. When using remote sense compensation, all the resistance, parasitic inductance and capacitance of the
system are incorporated within the feedback loop of this module. It can make an effect on the module's
compensation, affecting the stability and dynamic response. A 0.1uF ceramic capacitor can be
connected at the point of load to de-couple noise on the sense wires.
5. Recommend the connection of remote sense compensation as below figure. There are a resistor RS+
(51.1 ohm) from Vo+ to Sense+ and a resistor RS- (51.1 ohm)) from Vo- to Sense- inside of this module.

6. If not using remote sense compensation, please connect sense directly to output at module's pin, that is,
connect sense+ to Vo+ and sense- to Vo- at module's pin, the shorter the better. see below figure.

Output Trim Equations
Equations for calculating the trim resistor are shown below. The Trim Up resistor should be connected between
the Trim+ pin and Trim- pin.
The Trim Up resistor is NIL,Vout=0.6V
Maximum trim up voltage is 5V.
The total voltage increased by trim and remote sense should not exceed 10% of the nominal output voltage.

Over Current Protection
To provide protection in a fault output overload condition, the module is equipped with internal current-limiting
circuitry. If the overcurrent condition persists, the module will shut down into hiccup mode and restart. The
module operates normally when the output current goes into specified range.

Over Voltage Protection
The output overvoltage protection consists of circuitry that monitors the voltage on the output terminals. If
the voltage on the output terminals exceeds the over voltage protection threshold, the module will shutdown
into latch off mode. The overvoltage latch can be reset by either cycling the input power or toggling the
on/off signal for one second at least.

Power Good
1. This module has a power good indicator output. Power good pin used positive logic and is open collector.
2. Power good pin can sink 10mA.
3. The maximum voltage pulled up externally on Power Good pin should not exceed 30V.
4. When the output reaches 90% of the nominal set-point, the power good pin will be pulled high.
