SNVSBJ0A December 2019 – June 2020 LM5170
The LM5170-based converter is designed to operate with two differential voltage rails like the 48-V and 12-V dual battery system, or a storage system having a battery on one end and the Super-Cap on the other end. When operating with bench power supplies, each supply should be capable of sourcing and sinking the maximum operating current. This may require to parallel an Electronic load (E-Load) with the bench power supply (PS) to emulate the batteries, as shown in Figure 71.
It can also be used with a voltage source on one end and a load on the other end if the outer voltage control loop is closed. The outer voltage loop can be implemented either with digital means like an MCU or with analog circuit, as shown in Figure 53 and Figure 54.
