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.

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 Iss [µA] Preset soft-start time [µs] 4.5 5.0 5.5 750 825 920 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 maximum output voltage from Trim and Sense function combined is 5.5VDC. Derating may be required when using Trim and/or sense functions. Css = tss x Iss - n x 3.3nF1.25V

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).
