MAX15059 Evaluation Kit

Evaluates: MAX15059A/MAX15059B

General Description

The MAX15059 evaluation kit (EV kit) demonstrates

the MAX15059 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 2.8V 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 + 5V to 76V by replacing a resis-

tor or adjusting the CNTRL voltage. The EV kit dem-

onstrates the IC’s APD fast current-limit, undervoltage-

lockout (UVLO), and thermal-shutdown features.

The EV kit also features an APD input load-simula-

tor circuit for current monitoring and step-response

measurements.

The EV kit comes with the MAX15059AETE+ installed,

but can also be used to evaluate the MAX15059BETE+.

Warning: Voltages exceeding 42V may exist on the

VOUT, APD, MOUT, and PGND PCB pads.
