UC1856-SP Datasheet (Texas Instruments) - Improved Current-Mode PWM Controller

UC1856-SP, Improved Current-Mode PWM Controller

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 t
