9.7 Power-Management Subsystem

The CC3235MODx and CC3235MODAx power-management subsystems contain DC/DC converters to accommodate the differing voltage or current requirements of the system.

The CC3235MODx and CC3235MODAx MCU is a fully integrated module-based WLAN radio solution used on an embedded system with a wide-voltage supply range. The internal power management, including DC/DC converters and LDOs, generates all of the voltages required for the module to operate from a wide variety of input sources. For maximum flexibility, the module can operate in the modes described in the following sections.
