UCC3803规格书详情
描述 Description
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.
特性 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
