1.65W DC/DC converter, input 6...28V, output 3.3V/500mA, SIP3

The R-78E series is a switching regulator module that offers all the advantages of a switching regulator (high efficiency, wide input range, accurate output voltage regulation) but at a low cost for production quantities. Due to the high efficiency of the R-78E of up to 91% at an output voltage of 5V/1A at the output, no heat sink is required. The compact TO-220 compatible SIP3 package measures only 11.6 x 8.5 x 10.4 mm, saving valuable space on the PCB. The warranty is 3 years.
