摘要
根据LED驱动芯片的应用场合和应用模式设计了一款脉冲式LED驱动芯片。该芯片自带3路PWM驱动输出,具有8位(256灰度等级)数据解析和2 048级对比度的显示性能。同时,完成的芯片具有自动整形转发技术,从而实现了芯片单线级联的功能。在实际应用中芯片级联个数仅受限刷屏技术要求,大大简化了应用电路的复杂度。所设计的驱动芯片的版图完全通过dracula的DRC和LVS验证。目前芯片已加工制作完毕,测试结果正常,完成了预定的功能。
According to the mode of application of the LED driver chip, a pulsed LED driver chip was designed. The chip comes with a 3-channel PWM drive data analysis output, with 8-bit（256 gray levels）, 2 048 levels contrast performance. In specific applications, the chip with forward auto-shaping technology to chip single-wire cascade function, and the cascading number only limited scraper technical requirements. The layout of the chip through dracula DRC and LVS verification completely. Now the chip has been manufactured and the test results show that the chip can meet the functional requirements.
