Zetex launches high power Mini LED driver

Analog signal processing and power management solutions supplier Zetex Semiconductors, recently launched a new high power micro LED drive - ZXLD1350. ZXLD1350 to set the output current with a separate internal resistor, greatly simplifying the driving process of high power LED. The driver operates from 7V to 30V input voltage, capable of generating up to 350mA of adjustable output current, supporting links containing up to eight 1W LED. The switching regulator uses 2.9 x mm 2.8 TSOT23 five pin package, each component are tightly integrated, suitable for the space of the most limited application environment. The components of a 30V NDMOS switch, integrated into the +/-4% can provide precise current control of the high-end current sensing circuit, with four external circuit components to support. Zetex chief sales and marketing director Frank Marx pointed out that the efficiency of this LED drive can reach a maximum of 95%, all depends on the type and effect on the value of external components. In addition, the typical components of the shutdown current is very low, only 15 A, so the energy saving effect is excellent, effectively extend battery life. ZXLD1350 operating temperature range from 40oC to +105oC, temperature tolerance is 20% higher than similar solutions. In addition, it can support the continuous supply voltage 30V and 40V surge voltage, applied to the most stringent industrial or automotive applications. LED lighting applications generally require photometric calibration or more complex control efficiency, therefore, ZXLD1350 in particular to provide designers with a variety of control strategies. The multifunction control pin on the component is provided on the chip by using a DC voltage or a PWM waveform - PWM filter to provide an output current trimming function. Only when a capacitor is added between the control pin and the ground, the inherent soft start time of the ZXLD1350 can be prolonged. If you want to turn off the component output, you can introduce a logic low signal on the pin.
