DC2215A 演示电路采用 LTC3126,这是一款具有集成无损输入 PowerPath 的同步降压转换器。引脚可选 (JP2) 理想二极管“或”和优先输入模式以及可编程欠压锁定阈值可提供对输入源之间转换的控制。独特的全 N 通道架构可提供从两个输入源之一到可编程输出电压的高效操作。在此应用中,VIN1 上的有效输入电压范围设置为 4.3V 至 42V,VIN2 上的有效输入电压范围设置为 6V 至 8.4V,为各种应用和电源提供灵活性和电压裕度
说明
-
DC2215A, Demonstration Circuit features the LTC3126, a synchronous buck converter with an integrated lossless input PowerPath. Pin selectable (JP2) ideal diode-OR and priority input modes, with programmable under voltage lockout thresholds provide control over the transition between input sources. The unique all N-channel architecture provides efficient operation from either of two input sources to a programmable output voltage. In this application the valid input voltage range is set to be from 4.3V to 42V on VIN1 and from 6V to 8.4V on VIN2 providing flexibility and voltage margin for a variety of applications and power sources
