Product Number: MAX 14690 evaluation kit
Software Version: NA
Hi,
I am following to datasheet of MAX14690 EV kit on page 1 Quick start Procedure. According item 10 I writing 0xE8 to 0x0F doesn't turn on B2OUT. Only if I short connect both PFN1 and PFN2 to high during 3.7V on B2OUT start up to 2.2v. But after I can not turn off or change voltage level. Regarding B1OUT I have also to short both PFN1 and PFN2 during 3.7V on. Nevertheless, after I can control this buck using I2C controller. I am feeling I do something wrong during power up of the PMIC device. However I can understand what. Could you provide details how should I implement power up procedure
Thank you
