LM3434

具有高频明暗调节的常见阳极高亮度 LED 驱动器

The LM3434 is an adaptive constant on-time DC/DC buck (step-down) constant current controller (a true current source). The LM3434 provides a constant current for illuminating high power LEDs. The output configuration allows the anodes of multiple LEDs to be tied directly to the ground referenced cha ·Operating Input Voltage Range of –9V to -30V w.r.t. LED Anode\n ·Control Inputs are Referenced to the LED Anode\n ·Output Current Greater than 6A\n ·Greater than 30kHz PWM Frequency Capable\n ·Negative Output Voltage Capability Allows LED Anode to be Tied Directly to Chassis for Maximum Heat Sink E;
