Hi Teams
I am designing a product using the 9151 SIP.
According to the specifications, the operating voltage ranges from 3 to 5V.
From the hardware design guide, I learned that the 9151 VDD needs to be at least above 3.2V. However, the range from 3.2V to 5V is still quite wide. If the power consumption is 100mA across the range, the peak power difference can be as much as 0.18W.
May I ask what functions are affected by the voltage difference within this range? If my battery provides 3V, and I want to achieve the best RF performance, would you recommend boosting the voltage to 3.3V, 3.7V, or even higher?
