Product details

It supports multiple topologies — Flyback, SEPIC, Step-Down (Buck), and Step-Up (Boost) — making it a single-part solution for a range of automotive LED strings from daytime running lamps to high-beam headlights. The controller operates from a 5V to 65V supply, covering 12V and 24V battery systems with margin for load-dump transients. Switching frequency is programmable from 100kHz to 1MHz, letting the designer trade inductor size against switching loss. Dimming can be either analog (linear current adjust) or PWM, both supported natively.

The AEC-Q100 grade is often a non-negotiable requirement for automotive lighting BOMs.

The AEC-Q100 qualification means it is already qualified for automotive OEM BOMs, reducing requalification risk.

Frequently asked questions

Does MAX16833AUE/V+T support SEPIC topology?

Yes, SEPIC is one of the supported topologies, along with Flyback, Step-Down (Buck), and Step-Up (Boost). This makes it suitable for wide-input-range automotive LED drivers where the input voltage can be above or below the LED string voltage.

Is MAX16833AUE/V+T suitable for high-brightness LED headlights?

Yes, the AEC-Q100 qualification, 65V maximum supply, 125°C operating temperature, and support for Boost and SEPIC topologies make it well-suited for high-brightness automotive LED headlight applications where the LED string voltage may exceed the battery rail.

What is the difference between MAX16833AUE/V+T and MAX16833AUE+?

The MAX16833AUE/V+T carries AEC-Q100 automotive qualification (indicated by the "/V" suffix) and is supplied in tape-and-reel packaging ("T" suffix). The MAX16833AUE+ is the non-automotive-grade version, typically in tube packaging. Functionally the controller core is the same, but only the "/V+T" variant is qualified for automotive BOMs requiring AEC-Q100.
