Overview

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
  • Super-capacitor voltage range: 0.9 V to 2.7 V
  • Maximum output power: 3.8 V, 2A
  • High efficiency
  • Small size
  • Approximately 0.8-A high-current linear charger
