MAX15059 Evaluation Kit  
General Description  
Features  
Sꢀ 2.8V_to_5.5V_Supply_Voltage_Range  
Sꢀ 70V_Output_Voltage_(Approximate)  
Sꢀ 0_to_4mA_Output_Current  
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.

Sꢀ Fully_Assembled_and_Tested  
The EV kit also features an APD input load-simula-  
tor circuit for current monitoring and step-response  
measurements.  
Ordering Information  
The EV kit comes with the MAX15059AETE+ installed,  
but can also be used to evaluate the MAX15059BETE+.
