ZLED7030

High Current 40V LED Driver with Switch Dimming ZLED7x30 Datasheet Brief Description The ZLED7x30 continuous-mode inductive stepdown converter family is one of our ZLED LEDcontrol ICs. It is designed for applications requiring high brightness and high current. The ZLED7x30 can efficiently drive a single LED or multiple series-connected LEDs from a voltage input higher than the LED forward voltage (Vin = 8.5 to 40VDC). It provides an adjustable output current (1.2A maximum), which is set via an external resistor and controlled by the ZLED7x30’s integrated high-side output current-sensing circuit and high speed internal 40V power switch. Its low conducting impedance ensures high system efficiency. The ZLED7x30 provides a switch dimming function. It detects external switch action to adjust output current, allowing dimming functionality to be achieved without changing the original lighting system circuitry. The switch dimming is implemented in either twolevel mode or three-level mode. ...
