Note 1:
DCDC converter enables once PSWITCH connected with VIN supply. Once DCDC converter
started PSWITCH can be reconnected to GND without disrupting the DCDC converter operation.
Note 2: While DCDC converter is running in either Buck or boost mode, V1P8 is I/O level for MKW41z.
In Buck mode, V1P8 cannot output voltage greater than VIN supply voltage. V1P8 can provide a
limited number of additional peripheral devices which connect directly to the MKW41z’s IO due to
low output current. Please refer MKW41z datasheet for output current.
