Product details

Wide-input buck for industrial and automotive rails

500 mA output is the hard ceiling.

Package and mounting — plan for reflow

The 10-TDFN (3x2 mm) exposed-pad package needs reflow or a hot-air station. This is not a hand-solder field swap part — the thermal pad under the package is the main heat path, and getting it right without a reflow profile is unreliable. Plan for a pick-and-place pass and a reflow oven. Without that, the 125°C junction rating is academic — the part thermally limits well below the spec.

It carries ROHS3 compliance, so it passes into European and RoHS-restricted markets without exemption paperwork.

Frequently asked questions

Is MAX17501HATB+T a replacement for MAX17501E?

The MAX17501E is a different variant in the same family. The 'HATB+T' suffix indicates the 10-TDFN package and tape-and-reel packaging. Pin compatibility between the two depends on the package — the MAX17501E may come in a different case. Check the package codes on both before assuming a drop-in swap.

What output voltages can MAX17501HATB+T generate?

The output is adjustable from a minimum of 0.9V up to a maximum of 55.2V, set by an external resistor divider. Common rails like 1.8V, 3.3V, 5V, 12V, and 24V are all within range.
