SGM3751/SGM3752/SGM3756 抗振铃降低EMI的背光驱动
日期：2019-2-20摘要：SGM3751/SGM3752/SGM3756 抗振铃降低EMI的背光驱动
圣邦微电子（SGMICRO）最新推出一系列抗振铃降低EMI的背光驱动产品SGM3751/2/6 （支持小封装，PWM调光最低占空比可以支持0.5%）。该系列产品工作电压范围在2.7V ~ 5.5V，SW开关电流支持到1.5A，其中SGM3752属于SOT封装系列、SGM3751/6属于DFN封装系列。
应用开关型背光驱动做产品设计经常受EMI困扰，实验证实传导是影响手机性能的主要EMI模式。SGMICRO潜心研制出低EMI背光驱动SGM375X系列，开创性地以独到精确振铃吸收抑制EMI，改良了利用减缓开关时间抑制EMI的传统方式，减少传统方式带来的效率损失。该系列产品支持软启动功能，支持过热保护，可广泛用于一系列带有屏幕显示并且对低亮度显示以及RF骚扰抑制有要求的产品应用中。
圣邦微电子推出的背光驱动产品系列，属于无公害无铅环保产品，温度范围达到扩展的工业标准-40℃到+85℃，采用绿色TSOT-23-6以及TDFN-2×2-6L小封装，适用于自动化SMT生产及手工实验室验证。
