UCC2802QDRQ1
Low-Power BiCMOS Current-Mode PWM
500-µA Typical Operating Supply Current Operation to 1 MHz Internal Soft Start Internal Fault Soft Start 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 drive
components required for off-line and dc-to-dc fixed frequency current-mode switching power supplies with
minimal parts count.
These devices have the same pin configuration as the UC2842/3/4/5 family and also offer the added features
of 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 reference
parts such as the UCC2803 and UCC2805 fit best into battery operated systems, while the higher reference
and the higher UVLO hysteresis of the UCC2802 and UCC2804 make these ideal choices for use in off-line
power supplies.
The UCC280xQDRQ1 series is specified for the automotive temperature range of −40�C to 125�C, and
qualified in accordance with AEC-Q100 stress test qualification for integrated circuits.
