*Due to Vout/Vin ratio core voltage may have to be stepped down from 3.3-V I/O<br />
I/O supply 3.3 V, current up to 500 mA<br />
Core supply down to 1.8 V, current up to 1 A<br />

For additional power supply designs for TI <strong>DSP</strong>s, please visit www.ti.com/dsppower.<br />
Note: The TI power devices recommended here are based on standard operating conditions. System designers should use device power estimation tools in conjunction<br />
with overall application level power requirements to ensure an adequate power supply design is used.<br />
