GSM module back up power reference design for smart meters
Description
TIDA-050021 delivers a back-up power reference design for the GSM module. By adding a simple charge-pump circuit: this reference design can support 3.8-V: 2-A output power even when the super-capacitor voltage drops to 1 V. This allows the energy stored in the super capacitor to be used to the maximum.
Features
