Product Descriptions
The UCC280x family of high-speed, low-power integrated circuits contain all of the control and drive components required for off-line and DC-to-DC fixed frequency current-mode switching mode power supplies with minimal parts count.
These devices have the same pin configuration as the UCx84x family, and also offer the added features of internal full-cycle soft start and internal leading-edge blanking of the current-sense input.
Product Features
? 100-μA typical starting supply current
? 500-μA typical operating supply current
? Operation up to 1 MHz
? Internal soft start
? Internal fault soft start
? Internal leading-edge blanking of the current sense signal
? 1-A totem-pole output
? 70-ns typical response from current-sense to gate drive output
? 1.5% tolerance voltage reference
? Same pinout as UC3842 and UC3842A
Product Applications
? Switch mode power supplies (SMPS)
? DC-to-DC converters
? Power modules
? Automotive PSU
? Battery-operated PSU
