Specifications of MAX6765EVKIT+

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

This EV kit can also be used to evaluate the MAX6766–
MAX6774. The MAX6766 uses the 6-pin TDFN footprint
(U1) on the EV kit and the MAX6767–MAX6774 use the
8-pin TDFN footprint (U1a). Each of these parts shares
the same pin connections except for pin 4. R2, R3, J2,
and J3 work differently depending on the part. See Table
2 for the modifications needed for a particular part.
The MAX6769/MAX6770 have a RESETIN comparator
that asserts RESET if the voltage falls below the com-
parator threshold. The threshold voltage on IN can be
set using the following formula:

With the MAX6767–MAX6774, OUT provides regulated
DC at a voltage set by jumper J5, which selects either
the fixed output voltage or the output voltage set by
resistive dividers R5 and R6. This can easily be
changed according to the following equation:
