Texas Instruments UCC2 Manuals

The UCC2813-0/-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 UCC2813-0/-1/-2/-3/-4/-5 family offers choice of maximum duty cycle and critical voltage levels. Lower reference parts, such as the UCC2813-3 and UCC2813-5, fit best into battery-operated systems, while the higher reference and the higher undervoltage lockout (UVLO) hysteresis of the UCC2813-2

The UCC3807 family is a programmable maximum duty cycle PWM controller designed for off-line and dc-to-dc fixed frequency current mode switching power supplies. It features high speed, low power consumption, internal full cycle soft start, and internal leading edge blanking of the current sense input.

The UCC3809 family is an economy low power integrated circuit designed for off-line and isolated DC-to-DC fixed frequency current mode switching power supplies. It features user programmable soft start, maximum duty cycle, accessible 5V reference, undervoltage lockout, and more.

The UCC1800/1/2/3/4/5 family is a group of high-speed, low-power integrated circuits designed for offline and DC-to-DC fixed frequency current-mode switching power supplies. They feature internal soft start, internal fault soft start, and internal leading-edge blanking of the current-sense signal.

The UCC2813-0/-1/-2/-3/-4/-5 family is a series of high-speed, low-power integrated circuits designed for offline and DC-to-DC fixed frequency current-mode switching power supplies. They have features such as internal soft start, internal fault soft start, and internal leading-edge blanking of the current-sense signal.
