Smart meter PLC module backup power supply reference design


Design files


The TIDA-050033 reference design demonstrates the backup power supply solution for smart meter PLC module. By using a cost-effective boost converter TLV61048, minimum operating voltage is extended to maximize super capacitor usage rate. Smaller size (lower capacitance) super capacitor could be selected hence the total bill of material (BOM) is reduced.

  • Smaller sized super capacitor can be used to achieve same load delivery
  • High efficiency
  • Super capacitor minimum operating voltage: 1.3V
  • Approximately 60mA linear charger
Output voltage options TIDA-050033.1
Vin (Min) (V) 1.3
Vin (Max) (V) 2.5
Vout (Nom) (V) 12
Iout (Max) (A) .2
Output Power (W) 2.4
Isolated/Non-Isolated Non-Isolated
Input Type DC
Topology Boost- CCM
