详细看了该芯片的资料, 英文的,有点理解不透.
资料标题说 5V/6A 高效升压电源芯片,  误以为是6A 电流持续输出呢? 但资料还提到:
It integrates 6-A, 21-mΩ and 18-mΩ power switches, which is capable of delivering up to 2.4-A output current at 5-V
output with the 2.5-V input supply
貌似只是有21-mΩ and 18-mΩ可以达到6A 的功率开关,并不是持续输出6A电流,而是2.4A
此外 资料中还有:The TPS61230A is designed to operate from an input voltage supply range between 2.5 V and 4.5 V with a maximum output current of 2.4 A
所以,感觉被文档标题误导了.  大家有用过该芯片的么?多谢
