一种新的数字可调直流升压系统设计
Design of Digital Adjustable DC - DC Boost System
摘要
Abstract
At present the wide range boost system adopts mostly transformer, however it is always trapped in the problem of coupling and inaccurate boost, and cannot satisfy the requirement in the high precise filed. To solve this problem, we designed a boost system using the digital IC chip MAX1771 and programmable digital potentiometer AD5241, which has abilities of digital adjustable, wide range,and pulse frequency modulation (PFM) manner. This system achieved the multistage stable output from 12 V to 120 V. So, it can be applied to wide range boost field such as high voltage serial programming (HVSP) and intensity adjustment of medical equipment.关键词
