LM3433SQ-14AEV Datasheet PDF - TI

●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
