ZLED7000-ZI1R

The ZLED7000-ZI1R is a LED Driver IC for illuminated LED signs and other displays. It is an inductive step-down converter that is optimal for driving a single LED or multiple LEDs (connected in series) from a voltage source greater than the voltage rating of the LED. The ZLED7000 operates in continuous mode. Capable of operating efficiently with voltage supplies ranging from 6 to 40VDC, it is ideal for low-voltage lighting applications. The ZLED7000 minimizes current consumption by remaining in a low-current standby mode (output is off) until a voltage of ≥0.3V is applied to the ADJ pin. In operating mode, the ZLED7000 can source LEDs with an output current of ≤750mA (≤30W of output power) that is externally adjustable. The ZLED7000 is integrated output switch and high-side current sensing circuit use an external resistor to adjust the average output current.

• Capable of up to 95% efficiency
• Integrated 40V power switch
• One pin on/off or brightness control via PWM or DC voltage control signal input
• 1200:1 Typical dimming rate
• Output current accuracy of 5% (typical)
• Built-in thermal shutdown and open-circuit protection for LED
• Very few external components needed for operation
