Maxim MAX15054 LED驱动方案
Maxim 公司的MAX15054是高边N沟MOSFET驱动器,由CMOS逻辑电平控制,从输入到输出的传输延迟为12ns,输入电压高达60V,峰值源和吸电流为2A,主要用于单串和多串HB LED驱动器,DC/DC转换器的高边驱动器和LED背光驱动器.本文介绍了MAX15054主要特性,方框图和应用电路.
The MAX15054 is a high-side, n-channel MOSFET driver for high-voltage applications capable of switching at high frequencies. This device is controlled by a CMOS logic-level signal referenced to ground and features a very short (12ns, typ) propagation delay from input to output. The high-voltage operation and high source/sink-current capability make the MAX15054 ideal for HB LED drivers and DC-DC converters.
The MAX15054 is well suited to complement other Maxim LED driver products such as the MAX16814, MAX16838, MAX16833, MAX16834, and MAX16826. The MAX15054 adds a high-side driver to those products that include only a low-side driver; it then allows for buck-boost configurations for multistring drivers similar to the MAX16814, MAX16838, and MAX16826, and for buck-boost conversion with output referenced to ground for single-string drivers such as the MAX16834 and MAX16833.
The MAX15054 is available in the industry-standard 6-pin SOT23 package and operates over the -40℃ to +125℃ automotive temperature range...
