采用 LiSoCL2 电池的 GPRS 调制解调器的电源参考设计
TIDA-01387
概述
This design demonstrates how to power GPRS modems in smart meters using LiSoCL2 batteries. GPRS modems require peak current of up to 2A during transmission. This design reduces the peak load requirements on the battery by using the TPS61021A boost converter and a 20F super capacitor to provide the required transmit current. This reduces the overall cost of the system by allowing the use of lower cost LiCoCL2 batteries while maintaining a 10-year lifetime.
特性
- 0.7V to 4V input voltage range
- Small boost converter solution
- Efficiency is higher than 85% with 3V input voltage
- More than 2A output current capability with 2.8V input
- Ouput voltage dip less than 200mV
