Diodes introduces a new multi-topology LED driver that enhances the performance of high-brightness automotive, industrial and commercial lighting systems. The latest ZXLD1374 LED drivers operate in buck, boost, and buck-boost modes, and with an integrated 60V power MOSFET switch, can generate up to 1.5A of maximum LED current. The IC uses high-side current sensing and a patent-pending control loop for high-precision LED string current control.
With a wide input voltage range of 6-60V and a typical 1% output current tolerance across all topologies, this driver supports the high current levels required for high-brightness LED systems and the tight brightness between different lamps. match. In addition, the device implements dynamic LED thermal management through a dedicated external thermistor input and reports LED driver and load status through fault diagnostic output for higher LED reliability and longer life.
The ZXLD1374 also features dedicated DC dimming and pulse width modulation pins for a dynamic dimming range of 1000:1 at 500Hz, ensuring high-precision color mixing control and optimal resolution at low brightness. The IC's 1MHz switching frequency with 100kHz low frequency clamps helps to reduce the size of external inductors and simplify the design of any input EMI filter.
The product uses a brushless motor, which has excellent stability, drives the operation of the fan blades, and increases the wind power by more than 80%. 360° manual rotation can achieve a large area of cooling and comfort. The wind is loud and the sound is light, does not affect sleep and mood, and enjoys a soft and comfortable breeze.
