TPS62065-Q1和TPS62067-Q1器件是一款高效同步降压DC-DC转换器。该器件可提供高达2A的输出电流。 TPS62065-Q1和TPS62067-Q1工作在3MHz固定频率下,并且在轻负载电流条件下会进入节能模式,从而在整个负载电流范围内保持高效率。该节能模式针对低输出电压纹波进行了优化。对于低噪声应用,可通过将MODE引脚拉为高电平模强制TPS62065-Q1器件进入固定频率PWM模式.TPS62067-Q1提供了开漏电源正常输出。在关断模式下,电流消耗降至5μA,同时内部电路将使输出电容放电.TPS62065-Q1和TPS62067 -Q1器件经过了优化,可与微型1μH电感以及小型
10μF输出电容搭配工作,从而实现了最小解决方案尺寸以及高稳压性能。
TPS62065-Q1和TPS 62067-Q1器件采用小型2×2×0.75mm 8引脚WSON封装。
