question for ADSP-21261 power supply .

Hi Sir ,
 
We are using ADSP-21261 processor , 5V through TPS76801Q stabilized to 1.2V and supply inner-core voltage for ADSP-21261, but it turns very thermal after the chip keep working for 10 minutes . We would like to use LTC1877 to stabilize voltage as 21262 EZ-Kit , and we contact with Linear Technology , but they didn’t recommend that we use LTC1877 to supply power for ADSP-21261 processor .
 
Please give us your suggestion for power supply solution , thanks .
 
Best regards,
 
Windy
