Power Management Unit
Figure 10 shows the CYW20819 power management unit (PMU) block diagram. The CYW20819 includes an integrated buck
regulator, a digital LDO for the digital core, and an RF LDO for the Radio. The PMU also includes a brownout detector which places
the part in shutdown when input voltage is below a certain threshold.
