The LM5109A is a cost effective, high voltage gate driver designed to drive both the high-side and the low-side N-Channel MOSFETs in a synchronous buck or a half bridge configuration. The floating high-side driver is capable of working with rail voltages up to 90V. The outputs are independently controlled with TTL compatible input thresholds. The robust level shift technology operates at high speed while consuming low power and providing clean level transitions from the control input logic to the high-side gate driver. Under-voltage lockout is provided on both the low-side and the high-side power rails. The device is available in the SOIC and the thermally enhanced WSON packages.

TIDA-00476 — 用於能源儲存及 DC Home 解決方案的高效率、多用途雙向電源轉換器

TIDA-00476 由單個 DC-DC 功率級組成，可作為同步降壓轉換器或同步升壓轉換器使用，從而實現 DC 電源和儲能係統之間的雙向電力流動。該系統以同步降壓模式運行，作為最大功率點追蹤 (MPPT) 控制的 DC-DC 轉換器，可利用太陽能電池板或 DC 電源為電池充電。這個功率級也可作為同步升壓器運行，以驅動 DC 負載，並可配置定電流和定電壓限制 (CC/CV)，該負載的電源來自鉛酸電池等儲能係統。功率級由 MSP430 微控制器進行數位控制，該微控制器實現了功率級的閉環控制，並具有 MPPT、電池充電曲線和負載 DC 電源轉換所需的演算法。
