ZLED7720

High Current 40V LED Driver with Internal Switch ZLED7x20 Datasheet Brief Description Benefits The ZLED7x20 continuous-mode inductive stepdown converter family is part of our line of LEDcontrol ICs. It is designed for applications requiring high brightness and high current. It can efficiently drive a single LED or multiple series-connected LEDs from a voltage input higher than the LED forward voltage: Vin = 6 to 40 VDC. It provides an adjustable output current ≤1.2A, which is set via an external resistor and controlled by the ZLED7x20’s integrated high-side output current-sensing circuit and high speed internal 40V power switch. An external control signal, which can be a DC voltage, PWM, or microcontroller-generated waveform, on the ADJ pin can also be used to linearly adjust a continuous output current or to control a gated output current. High efficiency: up to 98% Single pin on/off and brightness control using DC voltage or PWM Very few external components needed for operation Footprint compatible with our ZLED7000 depending on the application. Available Support Evaluation Kit Physical Characteristics Operating junction temperature: -40°C to 125°C Switching frequency: up to 1MHz The output can be turned off by applying a voltage lower than 0.2V to the ADJ pin, which puts the ZLED7x20 in a low-current standby state. The ZLED7x20 enables diverse industrial and consumer lighting applications requiring high driving currents, wide operating voltage range, hi...
