数据: TPS548A20 具有 PMBus™ 接口的 1.5V 至 20V(4.5V 至 25V 偏置)输入、15A 同步降压 SWIFT™ 转换器 数据表 (Rev. A)
TPS548A20是一款具有自适应导通时间D-CAP3控制模式的小尺寸同步降压转换器。此器件使得空间受限类电源系统易于使用,并且外部组件数量较少。
此器件特有高性能集成MOSFET,精准0.6V基准和一个集成的升压开关。具有竞争力的特性包括:极低外部组件数量,快速负载瞬态响应,自动跳跃模式操作,内部软启动控制,并且无需补偿。
强制持续传导模式有助于满足高性能DSP和FPGA应用的严格电压调节精度要求.TPS548A20采用28引脚VQFN-CLIP封装,并且在-40°C至125°C的环境温度范围内额定运行。
