Description
This PDF datasheet is for the Unitrode UCC2813-1 PWM.
Unitrode UCC2813-1 Low Power BiCMOS Current Mode PWM
The UCC2813 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 UC3842/3/4/5 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 family offers a variety of package options, temperature range options, choice of maximum duty cycle, and choice of critical voltage levels.
The UCC2813-x series is specified for operation from –40 deg C to +85 deg C.
