Renesas Electronics ZLED7020
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.| Part No. | ZLED7020 |

DESCRIPTION
Benefits 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, high efficiency, and variable brightness control.
