Supercapacitor backup power supply for E-Meters reference design

This reference design automatically provides back-up voltages to an E-Meter during a power interruption. While the input voltage is between 10 V to 12 V, two buck controllers (TPS62147, TPS62173) generate 3.9 V at 2 A and 5 V at 150 mA. An optional synchronous boost generates 3.3 V at 50 mA. A (...)
