Power_03

Increased voltage ripple at low supply voltages when DC/DC converter is enabled

Revisions Affected:

Revision C and earlier

Details:

At supply voltages <2.0V, a hardware control module disables the DC/DC converter to maximize system efficiency. This module does not have enough hysteresis, causing approx 10 mV of ripple on the VDDR regulated power supply. Based on internal testing of the device, it is not anticipated that this erratum affects RF performance. However, these test results cannot ensure that a customer’s application or end equipment will not be affected.

Workaround:

Use the TI-provided Power driver (PowerCC26X2.c) which automatically disables the DC/DC converter when supply voltage is <2.2V.

The workaround is available in all SDK versions.
