Frequently Asked Questions
What input voltage range does TPS62933ODRLR support and how does it handle 24 V industrial bus transients?
TPS62933ODRLR accepts inputs from 3.8 V to 30 V, providing headroom to absorb 24 V industrial bus transients up to 28 V without damage. The current-mode PWM controller responds within a few microseconds to input voltage steps, maintaining output regulation even during 10 V load dump events common in 24 V factory automation wiring environments.
Which industrial or automotive applications are best matched to TPS62933ODRLR's 3.8 V to 30 V operating range?
Applications powered from 12 V automotive battery rails (9 V to 16 V range), 24 V industrial PLCs, and 28 V avionics ground-support equipment benefit from TPS62933ODRLR's wide input tolerance. Its PWM current-mode control also suits motor driver pre-regulators and sensor supply rails where load steps of 1 A or more must settle within 50 µs to avoid control system errors.
How does the 8-pin SO flat-lead package of TPS62933ODRLR compare to SOIC-8 for thermal dissipation at high input voltage?
The SO flat-lead package has an exposed bottom pad that provides a direct thermal connection to the PCB, reducing junction-to-board thermal resistance by approximately 15°C/W compared to a standard SOIC-8 with no exposed pad. At a 30 V input and 500 mA output, this difference can keep junction temperature 10°C to 15°C lower, improving long-term reliability above 85°C ambient in enclosed industrial enclosures.
