Overview
Product Details
This evaluation board is obsolete and no longer recommended.
Demonstration circuit 2118A is a combination step-down battery charger and step-up battery backup regulator using the LTC4040 monolithic system power manager. The DC2118A has an input voltage range from 4.8V to 5.5V with overvoltage protection (OVP) to 40V, as limited by the external MOSFET. The input current is monitored to prioritize the load up to the 2.5A threshold before charge current is reduced.
