** Standard part is without suffixes and Trim and CTRL pins are not fitted.
* add suffix /Pfor CTRL function with positive logic (1=ON, 0=OFF) including trim pin for single output
* add suffix /Nfor CTRL function with negative logic (0=ON, 1=OFF) including trim pin for single output
* add suffix -HC for premounted heatsink and clips
Ordering Examples
RP15-2405SA/P = 24V Input, 5V Output, Positive Logic CTRL pin and Trim pin fitted
RP15-4805DA-HC = 48V nput, ±5V Output, Heatsink fitted
The RP15-SA series are ultraminiature power DC/DC converters in a case half the size of industry standard 15W
converters. Despite their small size, the RP15-SA converters are fully specified devices with output currents up to
4 Amps, no minimum load, 1600VDC isolation and low ripple/noise figures. The outputs are also fully protected
against short circuits, overcurrent and overvoltage.
The RP15-SA series will find many uses in applications where board space and/or board height is at a premium.
