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
