Specifications of MAX6765EVKIT+

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

Before beginning, the following equipment is needed:
•
The MAX6765 EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Ensure that jumpers J1, J4, and J6 are shorted.
2) Connect the power supply to the IN and GND
3) Set the power supply output to 12V and observe LED1.
The MAX6765 operates from 4V to 72V and provides a
fixed or adjustable regulator output. The regulator can
source 100mA, subject to thermal dissipation limits.
Table 1 lists the function of each jumper on the EV kit.
OUT provides a regulated voltage at 5V.

Quick Start
Procedure
The reset output remains asserted for a certain minimum
period, which is controlled by jumper J6. If J6 is shorted,
the reset period is the default of 12.5ms. If J6 is open,
capacitor C4 sets the timeout period to 26.8ms, but this
can easily be changed using the following equation:
