DN-45 UC3846 UC3856 and UCC3806 Push Pull PWM Current Mode Control ICs
PDF, 27 Кб, Файл опубликован: 5 сен 1999
The UC3856 is a pin-for-pin-compatible high-performance bipolar version of the industry standard UC3846. It can replace the UC3846 with few circuit modifications and it features increased speed higher gate-drive current and reduced propagation delays. The UCC3806 is a BiCMOS pin-for-pin compatible ultra-low-power version ideal for battery low-power and high-speed applications. The UCC3806
