描述 Description

TLVM13610 是一款高度集成的 36V、 8A 直流/直流解決方案，集成了多個(gè)功率 MOSFET、一個(gè)屏蔽式電感器和多個(gè)無(wú)源器件，并采用增強(qiáng)型 HotRod? QFN 封裝。該模塊的 VIN 和 VOUT 引腳位于封裝的邊角處，可優(yōu)化輸入和輸出電容器的放置。模塊下方具有四個(gè)較大的散熱焊盤，可在制造過程中實(shí)現(xiàn)簡(jiǎn)單布局和輕松處理。

TLVM13610 具有 1V 到 10V 的輸出電壓，旨在快速、輕松實(shí)現(xiàn)小尺寸 PCB 的低 EMI 設(shè)計(jì)?？傮w解決方案僅需四個(gè)外部元件，并且省去了設(shè)計(jì)流程中的磁性和補(bǔ)償元件選擇過程。

盡管針對(duì)空間受限型應(yīng)用采用了簡(jiǎn)易的小尺寸設(shè)計(jì)， TLVM13610 模塊還提供了許多特性來(lái)實(shí)現(xiàn)穩(wěn)健的性能：具有遲滯功能的精密使能端可實(shí)現(xiàn)輸入電壓 UVLO 調(diào)節(jié)；電阻可編程開關(guān)節(jié)點(diǎn)壓擺率可改善 EMI。此外提供了集成式 VCC、自舉和輸入電容器，可提高可靠性和密度。該模塊自動(dòng)在恒定開關(guān)頻率 (FPWM) 或可變頻率 (PFM) 之間轉(zhuǎn)換，可實(shí)現(xiàn)更高的輕負(fù)載效率。包含 PGOOD 指示器，可實(shí)現(xiàn)時(shí)序控制、故障報(bào)告和輸出電壓監(jiān)測(cè)功能。
