The LMV393-N and LMV339-N are low-voltage (2.7 to 5 V) versions of the dual and quad comparators, LM393/339, which are specified at 5 to 30 V. The LMV331-N is the single version, which is available in space-saving, 5-pin SC70 and 5-pin SOT23 packages. The 5-pin SC70 is approximately half the size of the 5-pin SOT23.

The LMV393-N is available in 8-pin SOIC and VSSOP packages. The LMV339-N is available in 14-pin SOIC and TSSOP packages.

The LMV331-N/393-N/339-N is the most cost-effective solution where space, low voltage, low power, and price are the primary specification in circuit design for portable consumer products. They offer specifications that meet or exceed the familiar LM393/339 at a fraction of the supply current.

The chips are built with TI's advanced Submicron Silicon-Gate BiCMOS process. The LMV331-N/393-N/339-N have bipolar input and output stages for improved noise performance.

參考設計

PMP20587 — 反相降壓升壓參考設計

此參考設計使用 UCD3138064A 做為數位控制器,以控制二相二軌反相降壓升壓。此非隔離式轉換器用於無線電供電。輸入電壓範圍為 -35 V 至 -60 V。共有兩個輸出。軌 1 的預設輸出電壓為 32 V,最大電流為 8.5 A;軌 2 的預設輸出電壓為 48 V,最大電流為 5.5 A。輸出電壓可從 30 V 調整至 56 V。在進行部分元件變更和韌體變更後,硬體可用於電流模式控制或轉換模式控制,以增加功率並改善負載瞬態。分別提供了三種控制的測試結果。
