DC-DC升压(Boost)转换器就是输出電(diàn)压高于输入電(diàn)压的DC-DC;特性主要有(yǒu)電(diàn)流限制、输出電(diàn)流、支持 AVS/DVS 的输出電(diàn)压、开关频率、電(diàn)源正常信号、软启动、外部同步、工(gōng)作(zuò)模式(PFM/PWM、FCCM)以及保护模式(锁定模式、打嗝保护模式)和保护阈值(OVP、UVP、OCP、OTP)特性等。

MPS的DC/DC升压转换器可(kě)使用(yòng)单片锂電(diàn)池输入電(diàn)源。其高效的電(diàn)源方案能(néng)够提供更長(cháng)的電(diàn)池寿命、更少的热量和更小(xiǎo)的尺寸。随着半导體(tǐ)技(jì )术的发展,電(diàn)源稳压器的纹波越来越小(xiǎo),转换效率越来越高,输入電(diàn)压越来越低,输出電(diàn)压范围越来越广,功能(néng)日趋强大。MPS可(kě)提供 0.6V 至 36V 输入電(diàn)压范围,1.8V 至 55V 输出電(diàn)压范围,开关電(diàn)流限高达 22A。DC/DC升压转换器应用(yòng)范围覆盖仪表、汽車(chē)電(diàn)子以及消费类電(diàn)子诸多(duō)领域。
