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.
