Increased Voltage Ripple at Low Supply Voltages When DC/DC Converter is Enabled
Revision C
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 10mV 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.
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.
