UCC1803的产品详情：

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.

UCC1803的优势和特性：

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
