5.6 Power-Management Subsystem
The BDE-WF3235 power-management subsystem contains DC/DC converters to accommodate the differing
voltage or current requirements of the system.
The BDE-WF3235 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.
5.6.1 VBAT Wide-Voltage Connection
In the wide-voltage battery connection, the module can be directly connected to two AA alkaline batteries. All
other voltages required to operate the module are generated internally by the DC/DC converters. This scheme
is the most common mode for the module because it supports wide-voltage operation from 2.3 to 3.6 V.
