DN-45 UC3846, UC3856 and UCC3806 Push Pull PWM Current Mode Control ICs
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 may also replace the UC3846 with few circuit changes.
