Frequently Asked Questions
How does MAX16990AUBB/V+T handle the voltage transients present on a 12 V automotive bus?
MAX16990AUBB/V+T accepts an input voltage range of 4.5 V to 36 V, which covers both normal 12 V battery voltage and load-dump transients common in automotive environments, making it suitable for robust in-vehicle power supply designs.
Why does MAX16990AUBB/V+T switch at 2.5 MHz and what does that mean for inductor selection?
Operating at 2.5 MHz switching frequency allows designers to use smaller inductors and capacitors, reducing board area and BOM cost. At this frequency, even a compact boost stage can deliver several amps of output current with acceptable ripple using inductors in the low-microhenry range.
Can MAX16990AUBB/V+T drive a SEPIC converter to power 5 V loads from a varying 4.5 V to 36 V input?
Yes. The device natively supports both boost and SEPIC topologies, so a SEPIC configuration can produce a regulated 5 V output across the full 4.5 V to 36 V input range without additional controller ICs, simplifying the power supply design.
What package does MAX16990AUBB/V+T use and how does the exposed pad affect thermal performance?
The device is housed in a 10-pin MINI SO with an exposed pad, which allows direct thermal transfer to the PCB ground plane and improves heat dissipation compared to standard SO packages without exposed pads, supporting higher continuous power levels.
