TPS65251EVM
適用於 TPS65251 (具有 3 個 DC/DC 轉換器的 PMU，輸入電壓高達 18Vin) 的評估模組
TPS65251EVM
概覽
The TPS65251EVM is designed to help the user easily evaluate and test the operation and functionality of the TPS65251 buck converters (3-ch DC/DC; Ch1: 1.2 V, 3 A; Ch2: 1.8 V, 2 A; Ch3: 3.3 V, 2 A). The EVM converts a 4.5-V to 18-V input voltage designed to a regulated Ch1 = 1.2 V, Ch2 = 1.8 V, Ch3 = 3.3 V output voltage that delivers up to 3 A/2 A/2 A in a 6-mm x 6-mm 40-pins QFN package. The pick current mode control topology focuses on simplifing the PCB design optimize target application.
