Frequently asked questions
Is MAX17761ATC+T RoHS and REACH compliant?
REACH compliance is not separately stated in the available records.
What is the output current rating of MAX17761ATC+T?
The rated continuous output current is 1A. That is enough for a microcontroller rail, a CAN transceiver, and a handful of sensors — not a main power-stage regulator.
