LM3553: Drive 1 LED from 5Vin

Part Number: LM3553
Other Parts Discussed in Thread: LM36010

Hi, Team

My customer is working with LM3553 in a application of drive 1* LED. Power supply is 5V only.

LED: VF        ID

Max: 3.5V     350mA

Min:  2.9V     100mA

They are using the single LED schematic from datasheet.

 RSET is 39KOhm.

Since this device is a boost converter, if vin=5V, means output >=5V.

Does it can work as a constant current LED driver as we set?

Any risk for design?
