Product Introduction

The UC2856 is a high-performance version of the popular UC2846 Current Mode Controller family and is important for designing new applications for upgrades and intends to improve speed and accuracy. All input/output delays have been minimized, and current-sense output slew rate limits are used to reduce noise sensitivity. A fast 1.5 peak output stage has been added to allow for fast switching of power FETs.

The low-impedance TTL-compatible synchronous output is used as a synchronous input when the three-state function is implemented.

The grounding of the internal chip has been improved to reduce noise caused by the internal drive when large capacitive loads. This, combined with an improved differential current-sense amplifier, enhances noise immunity.
