Product details

At 25 mA output, this part is sized for auxiliary or always-on bias supplies — think microcontroller Vcore standby, CAN transceiver supply, or isolated-side housekeeping. It is not a main rail regulator. The 100 kHz to 2.2 MHz switching frequency lets the designer trade inductor size against efficiency; 2.2 MHz keeps the switching noise above the AM band, useful in RF-sensitive layouts.

The 10-uMAX/uSOP package (3.00 mm width) is a compact surface-mount footprint that suits space-constrained PCBs.

ROHS3 compliant. No single-source exposure — the Himalaya series has multiple pin-compatible density options if the load changes.

Frequently asked questions

Is MAX17550AUB+ obsolete or end-of-life?

No. The lifecycle status is Active, with no NRND or last-time-buy notice. It is suitable for new designs and ongoing production without obsolescence risk.

What is the output current of MAX17550AUB+?

The rated output current is 25 mA. This is a low-power bias supply — not a main rail regulator.

Is MAX17550AUB+ a direct replacement for MAX17550?

The MAX17550AUB+ is the same base part with a different package suffix (AUB+ vs. the base MAX17550). Verify the package code (10-uMAX/uSOP) and output current rating against your existing BOM before substituting. The electrical specifications are consistent within the Himalaya family.
