SL1571B 能夠輕松實(shí)現(xiàn)將單節(jié)鋰電池升壓至 7V，并輸出 1A 穩(wěn)定電流的卓越表現(xiàn)。其獨(dú)特的電路架構(gòu)，賦予了它快速的升壓響應(yīng)速度。當(dāng)美容面罩開啟時(shí)，SL1571B 能迅速達(dá)到穩(wěn)定工作狀態(tài)，使美容面罩燈即刻全功率運(yùn)行，節(jié)省用戶等待時(shí)間，開啟高效美容護(hù)理。

穩(wěn)定性是 SL1571B 的一大亮點(diǎn)。它內(nèi)置先進(jìn)的穩(wěn)壓和恒流控制模塊，無論鋰電池電量處于何種狀態(tài)，都能保證輸出電壓和電流的高度穩(wěn)定。這對(duì)于美容面罩燈至關(guān)重要，因?yàn)榉€(wěn)定的光功率輸出才能確保美容效果的一致性和可靠性。無論是刺激肌膚細(xì)胞活性的紅光，還是改善肌膚炎癥的藍(lán)光，SL1571B 都能提供持續(xù)穩(wěn)定的電力保障。

在能源利用上，SL1571B 同樣表現(xiàn)優(yōu)異。它擁有極高的轉(zhuǎn)換效率，在實(shí)現(xiàn)升壓供電的同時(shí)，有效降低了能量損耗，大大延長(zhǎng)了單節(jié)鋰電池的續(xù)航時(shí)間，減少用戶頻繁更換電池的麻煩，讓美容護(hù)理過程更加自在便捷。

DESCRIPTION

The SL1571Bis a high-power density, asynchronous boost 

converter with a 120mΩ power switch to provide a high 

efficiency and small size solution in portable systems. The 

SL1571B has input voltage range from 2.6 V to 5.5 V to 

support applications with different power supply. The device

has 3A switch current capability and can provide an output 

voltage up to 16V.

 The SL1571B also implements a soft-start function and an 

adjustable switching peak current limit function.

 In addition, the device provides 20V output overvoltage 

protection, and thermal shutdown protection.
