Description

The RPM-3.0 series is a 3A 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 97%, 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.

Vin, full load and after warm-up unless otherwise stated) 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.

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).
