Note:
1. In Buck mode, DC-DC converter needs 2.1V min to start, the supply can drop to 1.8V after DC-DC
converter settles
2. Analog supply voltage is same as VDD_IO (VDD_1P8OUT)
3. VDD_1V8 is internal configurable LDO output referred as VDD_1P8OUT.

DC-DC Converter
The MKW41z module contains an integrated DCDC converter which allows for three modes of operation
without additional components. When operating in DCDC Buck mode, power consumption from using
the radio can be reduced compared to DCDC Bypass mode. DCDC Boost mode allows the use of a single
alkaline or other low voltage source. While it is possible to switch between these modes in a single
design.
