TPS61310: dual LED(1.6A+1.3A) suitable part no.?

Dear TI Experts,

My customer has below requirment for LED driver:

1) Input Voltage 3.3V (or Li-battery directly power from 3.7~4.2V)

2) 2 channel total, 1 channel is capable of providing 1.6A peak current for laser LED (3.4~3.6V), driver will work with less than 1 sencond every time, most time it is in sleep mode to save power;

     another channel is similiar function only with less peak current around 1.3A

For this application, it seems to need 2pcs TPS61310 to drive 2 LEDs seperated.

Could you kindly help to give some advice about such requirment? Is there any single chip solution or better 2 chips solution?

Thanks a lot.
