Product Overview
Demonstration circuit 2118B is a combination step-down battery charger and step-up battery backup regulator using the LTC®4040 monolithic system power manager. The DC2118B 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.
- Overvoltage protection range from 5.5V to 40V (Limited by Q1 BVDSS) (charge mode)
- DCIN input power fail threshold of 4.8V at R2 = 357K, R27 = 121K, DCIN falling (backup mode)
