SLVSDF8B December 2016 – July 2017 TPSM84A22
PRODUCTION DATA.
The TPSM84A22 prevents the low-side MOSFETs from discharging a pre-biased output. During pre-biased startup, the low-side MOSFETs do not turn on until after the high-side MOSFETs have started switching. The high-side MOSFETs do not start switching until the internal soft-start reference voltage exceeds the voltage at the VADJ pin.
