DC1830B-A - LTC4000EUFD Demo Board | Battery Charger Controller/PowerPath Manager, 20V ≤ VIN ≤ 60V, VBATT = 3V to 30V @ up to 6.5A

Demonstration circuit 1830B is a battery charger controller and PowerPath™ manager with maximum power point control (MPPC) featuring the LTC®4000-1. MPPC extracts near maximum power from high impedance sources such as solar panels, wind turbines or fuel cells. MPPC is achieved by means of an input voltage regulation control loop. This board should be connected to a front-end DC/DC power supply for a complete charger solution. The DC1830B is customizable to handle a wide variety of applications with output voltages from 3V to 30V and output currents up to 6.5A with the PFETs supplied, and up to 60V and/or 13A with higher voltage rating and/or added PFETs. The reference design provided with DC1830B is targeted at 4-cell LiFePO4 (14.6V/5A) applications. The DC1830B loop compensation values were proven with the LTC3845A buck power converter shown and are typical for other applications. The output of this demo board was specifically tailored for a Tenergy 10A-hour battery, P/N 30207. Other voltages can be set by changing ROFB2 and RBFB2.
