UCC2804DTR General 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.
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
