CP2110
Alternatively, if 3.0 to 3.6 V power is supplied to the V
device with the voltage regulator bypassed. For this configuration, tie the REGIN input to V
regulator. A typical connection diagram showing the device in a self-powered application with the regulator
bypassed is shown in Figure 9.
The USB max power and power attributes descriptor must match the device power usage and configuration. See
application note “AN144: CP21xx Customization Guide” for information on how to customize USB descriptors for
the CP2110.
