T2081 POWERSUPPLY DESIGN CORE POWER REQUIREMENTS

Hi NXP'ians,

My query is regarding the T2081 core power(current) requirements and I've taken the reference design from T1040/2081 RDB.

As per the T2081 datasheet the  CORE&PLATFORM(VDD&S1VDD) current/power requirements for the T2081 processor is 10-15W (approx.) and the switching regulator used for the core voltage generation is Infineons "IR3473"(for 5V to 1V generation) which has only  6A (max.)continuous current supplying capability only.

 

So can I use the IR3473 DC-DC regulator for supplying core(VDD)&platform(S1VDD) as per RDB or suggest if any modifications are needed?
