DC-DC降壓恒流模式的產品(pin)主要是應用(yong)(yong)在(zai)輸(shu)入在(zai)電(dian)壓范圍在(zai)3.6V～100V以(yi)內的應用(yong)(yong)，輸(shu)出電(dian)流最(zui)(zui)大能支持到5A。采用(yong)(yong)buck電(dian)路結構，不同的電(dian)流檢(jian)測(ce)方式，多樣性的電(dian)路特點針對不同的應用(yong)(yong)可(ke)以(yi)讓用(yong)(yong)戶選(xuan)擇(ze)最(zui)(zui)佳的產品(pin)方案。
主要應用于LED車燈，LED裝飾照(zhao)(zhao)明，LED手持照(zhao)(zhao)明等(deng)。
