SYS Undervoltage-Lockout Comparator The SYS undervoltage-lockout (UVLO) comparator monitors VSYS and generates a SYSUVLO signal when the VSYS falls below UVLO threshold. The SYSUVLO signal is provided to the top-level digital controller. See Figure 7 and Table 6 for additional information regarding...
The input voltage is also monitored using a comparator and a 4-bit digital-to-analog converter (DAC) whose levels are set by the COMP_TH[2:0] bits in the LOFF register. The output of the comparators are stored in the LOFF_STAT register. These two registers are available as a part of...
The output of the comparator then “gates” timer 1 signal to trigger the second “timer 2” — which is a mono-shot timer set to max out at 15 us. This makes sure there is enough time left for the inductor to completely release its energy before the next cycle starts. You can ...

One of the voltages can be the internal reference (0-Series) or an internal reference scaled by an 8-bit DAC (everything else). This library, written by @MCUDude, provides a simple wrapper around the analog comparator(s) which makes their configuration easier and resulting code more ...
The CLK_EN bit in the CONFIG1 register enables and disables the oscillator clock to be output in the CLK pin. A truth table for these two pins is shown in Table 3. The CLK_EN bit is useful when multiple devices are used in a daisy-chain configuration. It is recommended that during ...
