Other Parts Discussed in Thread: AWR1843
Hello!!
I am considering the LP87524J-Q1 to power an AWR1843 radar. In this case, I need 3.3V, 1.8V, 1.2V and 1.1V. Reading the component datasheet I can see that the voltage for each regulator is configured via I2C, so I need to use the MCU to set the appropiate voltages... but I can't set the appropiate voltages the first time, because they are not properly configured. I have seen that this model have the values 0xFC for BUCK0_VOUT register, which is 3.3V (if I have calculated it properly), 0x75 for BUCK1_VOUT, which is 1.2V, 0x4D for BUCK3_VOUT, which is 1.0V but for the BUCK4_VOUT the default value is 0xCA, which is about 2.3V (if I have calculated it correctly) not the 1.8V I need in that case... Can I adjust those values by hardware, or do I need the MCU to configure this devices? Is possible to solve this issue and configure it correclty without damaging the AWR device?
Thanks in advance!!
