ultraboost Driver (New version 2021):

Ultraboost Driver:

• Constant current boost regulator. Adjustable current limit set by precision multi-turn trimpot and/or external Potentiometer
• Maximum output current 4000mA
  
• Can drive multiple series connected LEDs
• Operates from 8V to 50V (absolute maximum)
• Maximum output voltage 80V (open circuit protected)
• Protected against reverse polarity connection with high efficiency FET
  
• SHDN pin for low current standby
  
• High Speed PWM input
• Regulator requires input voltage to be LESS than output voltage (Boost driver)
• Board is 1.3" (33mm) in diameter. Maximum thickness is 8mm (PCB + inductor height). Components only on top side of the board. For higher power applications the board must be mounted to a heatsink with thermal pad material
• 10A maximum input current is recommended for good efficiency, refer to the technical section. Do not exceed 11A absolute maximum
