DCDC18R Boost Regulator BOO DCD C18 ST R R EGU LAT OR V in (11- 16)V G 18V V ou t G MAD E USA IN FIGURE 1. DCDC18R 1. General Description The DCDC18R Boost regulator is intended to accept an 11 to 16 VDC input and boost it to 18 VDC. Its main use is to boost automobile supply voltages to the 17 VDC minimum required to charge the batteries in the CR3000, CR5000, or CR23X LA bases. It can be conveniently bolted onto the side of the LA base next to the charger input. 2.

DCDC18R Boost Regulator measurement problems because the CR3000, CR5000, and CR23X have star ground connection at the ground lug. However, unwanted ground loops that induce single-ended measurement offsets will be generated if the terminals and the return side of the charging input are tied together because the return current to the DCDC18R will flow through the terminals.
