Part number:ZLED7320
Function: , 40-V LED driver delivers 98% efficiency
Description:The ZLED7320 continuous-mode inductive step-down converter family is part of our line of LED control ICs. It is designed for applications requiring high brightness and high current. The ZLED7320 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 ≤1.0A, which is set via an external resistor and controlled by the ZLED7320’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. The output can be turned off by applying a voltage lower than 0.2V to the ADJ pin, which puts the ZLED7320 in a low-current standby state. The ZLED7320 enables diverse industrial and consumer lighting applications requiring high driving currents, wide operating voltage range, high efficiency, and variable brightness control. It offers over-temperature and LED open-circuit protection. The ZLED7320 can also minimize bill-of-material costs because very few external components are required for most applications. Only a resistor, a diode, an inductor, and a capacitor are needed for a typical basic application. For easy evaluation of the ZSC7320, ZMDI offers the ZSC7320 Demo Kit, which includes a cascadable test board including one 5W white High Brightness LED, 5 ZLED7320 samples in DFN-5 package and documentation. Order using part number ZLED7320KIT-D1. Additional unpopulated cascadable test boards are also available.
