SLVSBV8E June 2013 – February 2020 LMZ31704
The LMZ31704 has been designed to prevent the low-side MOSFET from discharging a pre-biased output. During pre-biased startup, the low-side MOSFET does not turn on until the high-side MOSFET has started switching. The high-side MOSFET does not start switching until the slow-start voltage exceeds the voltage on the VADJ pin. Refer to Figure 25.
