Features

Receives nominal 12 V and raises it to 18 V
Attaches to side of CR23X or CR5000 rechargeable base
Outputs 1 A

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 CR23X and CR5000 rechargeable battery bases. It can be conveniently bolted onto the side of the rechargeable battery base next to the charger input.

* The boost regulator implements a soft-start circuit and typically starts regulating for input voltages greater than 10 V. Supply voltages below 10 volts pass directly to V out (through two Schottky diodes dropping the voltage by ~ 0.6 volts). With the DCDC18R operating at the maximum output current (18 V* 1A = 18 W) the input power required is up to 18 W / 0.8 efficiency = 22.5 watts; that is a maximum current of 2.25 Amps at 10 volts.
