LMZ34202EVM — 4.5V 至 42V、2A 降壓式電源模組評估板
TIDA-00783 — 空間最佳化寬輸入電壓三路輸出電源模組參考設計
TIDA-00783.1 參考設計是一種三輸出寬 Vin 電源模組設計。其以 6W 總功率提供 3.3V、1.8V 及 1.2V 輸出。配置針對空間受限的應用進行了最佳化。
TIDA-00808 — 具有超低 BOM 數量的空間最佳化 DC/DC 反相電源模組參考設計
TIDA-00808 是適用於工業應用的簡易 DC/DC 反相電源供應器參考設計。它在 4.5V 至 55V 之間採用廣泛輸入電壓,並在 1.75A 輸出時產生負 5V,峰值效率達 86%。由於此設計為反相,因此最大輸出電流會隨著輸入電壓增加而提升。此參考設計採用 LMZ36002 SIMPLE SWITCHER DC/DC 降壓電源模組,可實現精巧的解決方案尺寸與簡易性。電路板尺寸為 76.2 x 76.2mm(3 x 3 吋),而解決方案尺寸僅為 30.607 x 20.828mm(1.205 x 0.82 吋)。
TIDA-010011 — 用於保護繼電器處理器模組的高效電源供應架構參考設計
