Currently, power line communications (PLC) technology applied to smart meter is developing at a high speed. The new national grid standard requires that the 12 V voltage of the smart meter bus should report the necessary information within specified time after the bus voltage browns out. Thus, PLC module backup power supply is needed. The size of the backup power must be as small as possible due to limited space, at the same time, a cost effective solution is desired.
The TIDA-050033 reference design focuses on the above requirements. This reference design includes a linear charger, a super capacitor, a high step up ratio, high efficiency boost converter TLV61048 and a synchronous step down converter.
