PMC1010H数据手册Qualcomm中文资料规格书

描述 Description

PMC1010H’s “combo” architecture allows it to operate in either divide-by-two (DIV2) charge pump mode or 3-level-buck (3LBK) regulator mode. This unique combination marries the benefits of both topologies; thus, providing high efficiency for powering lower-voltage systems from higher-voltage battery configurations across the full load spectrum. The PMC1011H, on the other hand, does not operate in Div2 and therefore can provide a more tightlyly regulated output with less output voltage variation during extreme transient events. Both PMC1010H/ PMC1011H provide +18 V DC input withstand voltage and support a wide operating input range of 5 V to 16.5 V for 3S batteries and 5 V to 9 V for 2S batteries.
