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 oper-
ates 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 con-
figured 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 cur-
rent monitoring and step-response measurements.
WARNING: Voltages exceeding 42V may exist on
the VOUT, APD, MOUT, and PGND PCB pads.
