Evaluation Kit for the MAX15031

All versions are Not Recommended for New Designs. See Ordering Information for recommended replacements.

The MAX15031 evaluation kit (EV kit) demonstrates the MAX15031 APD biasing pulse-width modulation (PWM) step-up DC-DC converter with an internal power switch, current monitor, and adjustable current limiting. The step-up converter switches at 400kHz. The EV kit operates from a DC supply voltage of 2.9V to 5.5V and is configured to deliver approximately 70V and 0 to 4mA of current at the output. The output voltage can be configured from VIN + 1V to 76V by replacing a resistor or adjusting the CNTRL voltage. The EV kit demonstrates the MAX15031 APD fast current-limit, undervoltage lockout (UVLO), and thermal shutdown features.

The actual converter circuit's PCB footprint is 8mm x 18mm as required in BPON (broadband passive optical network) and GPON (gigabit passive optical network) applications and demonstrates the MAX15031's small, 16-pin TQFN package with exposed pad. The EV kit also features an APD input load simulator circuit for current monitoring and step-response measurements.

WARNING: Voltages exceeding 42V may exist on the VOUT, APD, MOUT, and PGND PCB pads.
