Description
The RPM-2.0 series is a 2A non-isolated switching regulator power module with a full set of features
including adjustable output, sequencing, soft-start control, on/off control, and power good signals. The
ultra-compact module has a profile of only 3.75mm, but with an efficiency of up to 98%, the device can
operate at full load in ambient temperatures as high as +105°C without forced air cooling. The package
is complete with 6-sided shielding for optimal EMC performance and excellent heat management.

OUTPUT VOLTAGE TRIMMING
The RPM series offers the feature of trimming the output voltage over a range between 0.9V and 6V by using external trim resistors. The values
for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary.

Sequencing Multiple Modules
The SEQ pin can be used to program the rising edge of the output voltage. An internal current source charges a soft-start capacitor which
is connected from the sequencing pin to GND. The following equation is used to calculate the soft-start capacitor:
Css = soft-start capacitor
Iss = sum of all soft-start currents of all sequenced modules
tss = required soft-start time
n = number of RPMs
I
ss

Note: there is a 3.3nF internal soft-start capacitor, and there are different constant
current sources in the modules which leads to different preset soft-start times.

The output voltage can be adjusted via the trim and

The maximum output voltage from Trim and Sense
function combined is 5.5VDC. Derating may be
required when using Trim and/or sense functions.

POSITIVE TO NEGATIVE
C1 and C2 may be added to reduced
ripple and should be fitted close to
the converter pins.
Notes:
Note8: RECOM Power Modules can also be used to convert a positive voltag into a negative voltage. Parameters such as
maximum Vin, efficiency and maximum operating temperature are reduced. Please contact RECOM for further details.

RPM(1)
To sequence multiple converters to start at the same time (set output voltage is reached at the same time), the following schematic may be used:
To sequence multiple power module start-up times the power good (PGood) pin and the CTRL pin may be used. In below schematic,
the RPM(n) starts after RPM(1) reaches its set output voltage and the power good signal is set to high which then enables RPM(n).
After RPM(n) reaches its set output voltage, it enables RPM(n+1).
