The LM3433SQ-14AEV is an evaluation board for LM3433, an adaptive constant on time DC to DC buck constant current controller designed to drive a high brightness LEDs (HB LED) at high forward currents. It is a true current source that provides a constant current with constant ripple current regardless of the LED forward voltage drop. The board canaccept an input voltage ranging from -9V to -14V with respect to GND. The output configuration allows the anodes of multiple LEDs to be tied directly to the ground referenced chassis for maximum heat sink efficiency when a negative input voltage is used.
● Operating input voltage range of -9V to -14V with respect to LED Anode
● Control inputs referenced to the LED anode
● Output current greater than 6A
● Greater than 30kHz PWM frequency capable
● No output capacitor required
● Up to 1MHz switching frequency
● Low IQ, 1mA typical
● Adaptive programmable ON time allows for constant ripple current
