ZLED7000 40V LED Driver with Internal Switch Datasheet Brief Description Features The ZLED7000, one of our ZLED Family of LED control Capable of up to 95% efficiency* ICs, is an inductive step-down converter that is optimal Operates in continuous mode with a wide input for driving a single LED or multiple LEDs (connected in range from 6 VDC to 40 VDC series) from a voltage source greater than the voltage Integrated 40V power switch rating of the LED. The ZLED7000 operates in continu- One pin on/off or brightness control via PWM or DC ous mode. Capable of operating efficiently with voltage voltage control signal input supplies ranging from 6 VDC to 40 VDC, it is ideal for low-voltage lighting applications. The ZLED7000 Switching frequency: 1MHz minimizes current consumption by remaining in a low- Dimming rate: 1200:1 (typical) current standby mode (output is off) until a voltage of Output current accuracy: 5% (typical) 0.3V is applied to the ADJ pin. Built-in thermal shutdown and open-circuit protection In operating mode, the ZLED7000 can source LEDs with for LED an output current of 750mA ( 30 watts of output Very few external components needed for operation power) that is externally adjustable.* The ZLED7000s Broad range of applications: outputs up to 750mA integrated output switch and high-side current sensing circuit use an external resistor to adjust the average SOT89-5 package output current. Linearity is achieved via an external control signal at the ZLED7000s ADJ pin, implemented Application Examples either as a pulse-width modulation (PWM) waveform for Illuminated LED signs and other displays a gated output current or a DC voltage for a continuous current.
