摘要
介绍了降压型(BUCK)变换器的开关管由高端置于低端,详细分析了降压型变换器高端驱动的问题和低端驱动方式,阐述了基于UC3842芯片降压型(BUCK)变换器控制系统的设计。该设计采用低端驱动方式,驱动方便,电路简单,容易实现。
The step-down （BUCK） converter was ‘introduced’ which the high-side switch tube is placed in the low-side. The problem of the Buck converter’s high-side drive and the low-side drive are analyzed in detail. The design of the BUCK converter control system based on UC3842 chip is elaborated. And the low-side drive was used which is convenience, simple and easy to implement.
