ZHCSBE2A August 2013 – October 2022 TPS54625
PRODUCTION DATA
TPS54625 has power-good open drain output. The power-good function is activated after soft start has finished. The power good function becomes active after 1.7 times soft-start time. When the output voltage becomes within –10% of the target value, internal comparators detect power good state and the power good signal becomes high. Rpg resistor value, which is connected between PG and VREG5, is required from 25 kΩ to 150 kΩ. If the feedback voltage goes under 15% of the target value, the power good signal becomes low.
