DCDC18R
DCDC18R
Orderable12 to 18 Vdc Boost Regulator
Overview
The DCDC18R Boost Regulator accepts an 11 to 16 Vdc input and boosts it to 18 Vdc, allowing a vehicle to recharge CR3000, CR5000, or CR23X sealed rechargeable batteries. The DCDC18R conveniently attaches to the side of the sealed rechargeable base next to the charger input.
Technical Description
Supply voltage from the vehicle is connected to the DCDC18R's Vin terminals. Regulated voltage to charge the data logger’s sealed rechargeable power supply are sourced from the Vout terminals.
Maximum Input Current
The boost regulator implements a soft-start circuit and typically starts regulating for input voltages greater than 10 V. Supply voltages below 10 V pass directly to Vout (through two Schottky diodes dropping the voltage by ~0.6 V). With the DCDC18R operating at the maximum output current (18 V * 1 A = 18 W), the input power required is up to 18 W / 0.8 efficiency = 22.5 W; that is a maximum current of 2.25 A at 10 V.
