Part Number: LM2775-Q1

Hi Champs,

 My customer is interested in LM2577-Q1 to supply 5V for TCAN1042 device from 3.3V rail.

System requires Ta=105C, and TCAN1042 consume 180mA at maximum when bus fault.

 While in clause “6.3 Recommended Operating Conditions” Ta is specified as 85C max, is it possible use LM2577-Q1 under Ta=105C condition if its Tj <125C is satisfied?

Best regards,

Nobuo
