UCC2803QDRQ1 TI
1 Features 1• Qualified for automotive applications • AEC-Q100 qualified with the following results: – Device temperature grade 1: –40°C to 125°C TA – Device HBM classification level 2: ±2 kV – Device CDM classification level C5: >1000 V • 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
2 Applications • Switch mode power supplies (SMPS) • DC-to-DC converters • Power modules • Automotive PSU • Battery-operated PSU 3 Description The UCC280x-Q1 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 leadingedge blanking of the current-sense input.
