Diodes company launched a new ZXLD1374 LED driver to enhance the high-brightness automotive, industrial and commercial lighting system performance. The drive uses step-down (buck), step-up (boost) and buck - boost (buck-boost) mode, with an integrated 60V power MOSFET switching, can produce the maximum LED current up to 1.5A. Meanwhile, high-side current sensing and control circuit patent-pending, can achieve high-precision LED string current control.
ZXLD1374 LED driver provides 6V to 60V wide input voltage range, and can be implemented in all the typical topology of the output current of 1% tolerance, so they can support high-brightness LED system for the high current levels, and different light intensity between the close Match. In addition, the external device through a dedicated thermistor input dynamic LED thermal management and reporting through the fault diagnosis output LED driver and load status, the LED to achieve higher reliability and longer life.
In addition, the drive is also equipped with a dedicated DC dimming (DC dimming) and pulse width modulation pin (PWM dimming pins), can be achieved in the 500Hz frequency, dimming 1000:1 dynamic range, to ensure that low-energy high brightness Control and precision blending the best resolution. ZXLD1374's 1MHz switching frequency of 100kHz with frequency clamp to help reduce the size of the external inductor to simplify any input electromagnetic interference filter (EMI filters) design.
