DESCRIPTIONThe UC2856isa high performance versionof the popular UC2846 andis
intended for both design upgrades and new applications where inputto
output delays have been minimized, and the current sense output
Fast 1.5-A peak output stages have been addedto allow rapid low impedance TTL compatible sync output has been implementedasa
sync input.
Internal chip grounding has been improvedto minimize internal noise caused when driving large capacitive
