DESCRIPTION  
The UC2856 is a high performance version of the popular UC2846 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.  
A low impedance TTL compatible sync output has been implemented with a 3-state function when used as a  
sync input.  
Internal chip grounding has been improved to minimize internal noise caused when driving large capacitive  
loads. This, in conjunction with the improved differential current-sense amplifier, results in enhanced noise  
immunity.  
Other features include a trimmed oscillator current (8%) for accurate frequency and dead-time control, a 1-V 5%  
shutdown threshold, and 4-kV minimum ESD protection (HBM) on all pins.
