the ucc2813-x-q1 device family of high-speed, low-power integrated circuits contains 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 uc284x device 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-x-q1 device family offers a variety of package options, choice of maximum duty cycle, and choice of critical voltage levels. devices with lower reference voltage such as the ucc2813-3-q1 and ucc2813-5-q1 fit best into battery operated systems, while the higher reference and the higher uvlo hysteresis of the ucc2813-2-q1 device and ucc2813-4-q1 device make these ideal choices for use in off-line power supplies.

the ucc2813-x-q1 device series is specified for operation from –40°c to 125°c.

参考设计

— 适用于医疗封装的反激式、线性稳压器 (5.75v@10ma)

此设计可提供隔离的 5v（两个）、3.3v、2.5v 及 -5v 输出。对于噪声敏感应用（如医学成像和数据采集），所有输出均可采用低压降 (ldo) 线性稳压器进行噪声过滤。
