UC1856-SP Overview
The UC1856 is a high-performance version of the popular UC1846 series of current-mode controllers, and is intended for both design upgrades and new applications where speed and accuracy are important. All input-to-output delays have been minimized, and the current sense output is slew-rate limited to reduce noise sensitivity. Fast 1.5-A peak output stages have been added to allow rapid switching of power FETs.
