非隔离DC-DC转换器模块UltraBK™

MYTxx系列采用了村田自主研发的实质无损开关电容器架构的2-stage PoL用稳压器模块。
本产品包括电感器在内的全部无源元件均集成在一个封装内。
在2芯/3芯电池或12V输入PoL应用中,配置了高效率、低纹波/低噪声特性的电压转换电路,在尺寸和高度两方面的解决方案皆实现了大幅削减。

※实质无损开关电容器架构:通过软开关电路,降低向电容器充电时的突入电流造成的损耗的电路技术。

技术指南

村田特有的降压转换两级架构

一种高度灵活的多级架构,包括与降压级相结合的“管道”级开关电容器网络(电荷泵)。

Virtually lossless stage irrespective of conversion ratio! Efficiency is largely independent of the difference between input and output voltage. Capacitors do most of the work, enabling greatly reduced inductor sizing. Uses low voltage FETs throughout the power train. Built on standard CMOS.

交错操作以降低纹波/EMI并实现更好的瞬态性能

Interleaved Charge Pump stage leads to Lower input ripple Lower EMI emissions Interleaved Buck Converter stage leads to Lower output ripple Better transient performance
