说明

TPS6286x 器件是具有 I2C 接口和 VSEL 接口的高频同步降压转换器。这些器件提供了高效、灵活和具有高功率密度的负载点直流/直流设计。该转换器在中高负载条件下以 PWM 模式运行,并在轻负载时自动进入省电运行模式,从而在整个负载电流范围内保持高效率。该器件还可强制进入 PWM 运行模式,以实现最小输出电压纹波。凭借其 DCS-Control 架构,这些器件可实现出色的负载瞬态性能并符合严格的输出电压精度要求。通过 I2C 接口和专用 VSEL 引脚,可快速调整输出电压,使负载的功耗适应相关应用不断变化的性能需求。该器件系列提供两个 VSEL 引脚和四个出厂预设电压,支持在没有 I2C 接口的情况下使用。
