PT1908 普誠 電流紋波去除器IC 用于LED恒流驅(qū)動
DESCRIPTION
PT1908 is a chip used in LED constant current driving to eliminate 100/120Hz current ripple.
PT1908 has good ripple elimination performance throughout the entire output current range and still has excellent dynamic response speed in fast dimming system applications.
PT1908 integrates a 40V N-channel MOSFET internally, and it is recommended to apply an output current of less than 120mA. Support thyristor dimming, low system cost, SOT23-3 package, SOT89-3 package
