Low-Power BICMOS Current-Mode PWM
−55°C to 125°C Enhanced Diminishing ManufacturingSources (DMS) Support Enhanced Product Change Notification Qualification Pedigree† ESD Protection Exceeds 200 V UsingMachine Model (C = 200 pF, R = 0) 100 μA Typical Starting Supply Current 500 μA Typical Operating Supply Current Component qualification in accordance with JEDEC and industrystandards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification
testing should not be viewed as justifying use of this component
beyond specified performance and environmental limits.
Current Sense Signal 1 Amp 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
descriptionThe UCC2800/1/2/3/4/5 family of high-speed, low-power integrated circuits contain all of the control and drivecomponents required for off-line and dc-to-dc fixed frequency current-mode switching power supplies withminimal parts count.
These devices have the same pin configuration as the UC2842/3/4/5 family and also offer the added featuresof internal full-cycle soft start and internal leading-edge blanking of the current-sense input.
The UCC2800/1/2/3/4/5 family offers choice of maximum duty cycle and critical voltage levels. Lower referenceparts such as the UCC2803 and UCC2805 fit best into battery operated systems, while the higher referenceand the higher UVLO hysteresis of the UCC2802 and UCC2804 make these ideal choices for use in off-linepower supplies.
