The UCC2813-x-Q1 family of high-speed, low-power integrated circuits contain all of the control and drive functions required for off-line and DC-to-DC fixed-frequency current-mode switched-mode power supplies having minimal external parts count. The UCC2813-x-Q1 family is a cost-reduced version of the UCCx80x family, with some relaxation of certain parameter limits. See Differences Between the UCC3813 and UCC3800 PWM Families for more information.
These devices have the same pin configuration as the UC284x and UC284xA families, and also offer the added features of internal full-cycle soft start and internal leading-edge blanking of the current-sense input. The UCC2813-x-Q1 devices are pin-out compatible with the UC284x and UC284xA families, however they are not plug-in compatible. In general, the UCC2813-x-Q1 requires fewer external components and consumes less operating current.
The UCC2813-x-Q1 series is specified for the automotive temperature range of −40°C to 125°C.
