TPS61021A: peak current issue

Part Number: TPS61021A

Hi all:

      In my design, i want to use a Lithium-Manganese battery(voltage range is form 1.5v-3v) as a power source for a dcdc boost power ic, and i will use the dcdc boost power ic  to driver a gsm RF module, due to the work mode of gsm system, the RF module need 3.8v input, and the peak current of this module is about 2A(the peak current continued time is abour 5us), so , i searched in TI's website and i find the tps61021a has the similar performance, but i am afraid whether tps61021a could afford the peak current of the gsm RF module?i want to know which power ic i can choice?
