com Brief Description The ZLED7000, one of our ZLED Family of LED control ICs, 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 VDC to 40 VDC, it is ideal for low-voltage lighting applications.
The ZLED7000 minimizes current consumption by remaining in a lowcurrent 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 (≤ 30 watts of output power) that is externally adjustable.
* The ZLED7000’s integrated output switch and high-side current sensing circuit use an external resistor to adjust the average output current.
Linearity is achieved via an external control signal at the ZLED7000’s ADJ pin, implemented either as a pulse-width modulation (PWM) waveform for a gated output current or a DC voltage for a continuous current.
