TAS5342LA: Relationship of PVDD and case temperature

Part Number: TAS5342LA

Hi

Is it likely that difference of PVDD would affect to Tc (case temperature) of the device in spite of same output power?

For example,

1. PVDD =12V, L/R has 12W/12W, that leads Tc=80C (Ta = 25C)
2. PVDD=19V, L/R has 12W/12W, that leads Tc=100C (Ta = 27C)

May it be occured with normal operation?

BestRegards
