illustrate

توفر هذه السلسلة من المنظمين LM2574 الدائرة المتكاملة المتجانسة جميع منظمات تبديل الوظائف النشطة (باك) ، مما يؤدي إلى تنظيم خط وحمل ممتاز بسعة تحميل تبلغ 0.5 أمبير. These devices are available in fixed output voltages of 3.3V and 5V and 12V, 15V, and adjustable output versions.

Requiring a minimum number of external components, these regulators are simple to use, with built-in frequency compensation and fixed-frequency oscillators.

توفر سلسلة LM2574 بديلا شائعا عالي الكفاءة للمنظمات الخطية ذات 3 أطراف. نظرا لكفاءتها العالية ، عادة ما تكون الأسلاك النحاسية على لوحات الدوائر المطبوعة مطلوبة فقط لتبديد الحرارة.

يمكن الحصول على المعيار المستقبلي لسلسلة المحث LM2574 المحسنة للاستخدام من العديد من الشركات المصنعة المختلفة. This feature greatly simplifies the design of switching power supplies.

Other features include ± guaranteed 4% tolerance of voltage and ± 10% oscillator frequency under specified output input voltage and output load conditions. External shutdown is included with 50μA (typical) standby current. The output switch includes cycle-by-cycle current limit and adequate protection against thermal shutdown during fault conditions.
