Product introduction

TPS60230 مضخة شحن تيار منظمة 5 قنوات و 125 مللي أمبير في حزمة QFN 3x3 للإضاءة الخلفية LED البيضاء

illustrate

تحسين مضخة الشحن TPS60230 ، تطبيقات شاشة LED ملونة بيضاء بإضاءة خلفية. يوفر الجهاز تيارا ثابتا ويتم ضبط كل مصباح LED بواسطة مقاوم خارجي. The supply voltage range is 2.7 V to 6.5 V and is ideal for all applications powered by a single Li-ion battery or three to four NiCm, NiMH or alkaline batteries. يمكن أن توفر TPS60230 ما يصل إلى 25 مللي أمبير لكل مصباح LED ، مع نطاق إدخال إجمالي يبلغ 125 مللي أمبير من 3.1 فولت إلى 6.5 فولت ، جهد عالي الكفاءة ، وهو مصدر تيار 1x / 1.5x يتم تنفيذه في تقنية التحويل الجزئي لبلد آلة Combi باستخدام جهد تسرب منخفض جدا. In addition, a current-controlled charge pump ensures low input current ripple and EMI.
