LM3488 عبارة عن منظم تبديل n-FET متعدد الاستخدامات منخفض الجانب لوحدات التحكم عالية الأداء. هذا مناسب لطبولوجيا الاستخدام التي تتطلب FETs منخفضة النهاية مثل التعزيز ، و flyback ، و SEPIC ، وما إلى ذلك ، بالإضافة إلى ذلك ، يمكن أن يعمل LM3488 بترددات تحويل عالية جدا لتقليل الحجم الكلي للحل. يمكن ضبط تردد التبديل ل LM3488 إلى أي قيمة بين 100 كيلو هرتز و 1 ميجا هرتز ، إما باستخدام مقاوم خارجي أو المزامنة مع ساعة خارجية. Current-mode control provides superior bandwidth and transient response, except for cycle-by-cycle current limiting. يمكن برمجة تيار الخرج بمقاوم خارجي واحد.
يحتوي LM3488 على ميزات مدمجة مثل الإغلاق الحراري وحماية ماس كهربائى وحماية الجهد الزائد. يقلل وضع إيقاف تشغيل الطاقة من إجمالي تيار الإمداد بمقدار 5 μA ويسمح بتسلسل الطاقة. Internal soft-start limits inrush current at startup.
Main specifications
- نطاق جهد إمداد واسع من 2.97 فولت إلى 40 فولت
- قابل للتعديل من 100 كيلو هرتز إلى 1 ميجا هرتز مع تردد ساعة متزامن
- ± 1.5% (overheated) internal reference
- تيار الاغلاق 5μA (درجة الحرارة الزائدة)
