为什么和如何实现频率提升, CCFL灯管罢工期间的DS3881/DS3882

资料介绍
DS3882控制器冷阴极荧光灯(CCFL)是背光的液晶显示器在汽车,工业和航空电子应用(液晶显示器) 。在这些应用中, CCFL灯管可以要求高罢工电压。虽然一些系统的设计标准影响罢工电压的,一个标准很容易被修改,增加灯泡罢工电压:灯泡罢工过程中提高工作频率。

APPLICATION NOTE 3941
Why and How to Implement a Frequency Boost During a CCFL Lamp
Strike on the DS3881/DS3882

Abstract: The DS3881 and DS3882 are controllers for cold-cathode fluorescent lamps (CCFLs) that backlight
liquid crystal displays (LCDs) in automotive, industrial, and avionic applications. In these applications the CCFL
lamps can require a high strike voltage. While several system design criteria affect the strike voltage, one
criterion is easily modified to increase the lamp strike voltage: boosting the operating frequency during the
lamp strike process.

This application note describes the need for increasing the CCFL controlle……
