UCC2801MDREP集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF中文资料

UCC2801MDREP属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由德州仪器制造生产的UCC2801MDREPDC-DC 开关控制器PMIC（电源管理集成电路）DC 到 DC 开关式控制器是用于高效率电路的稳压 IC，其配置为生成高于（突升或步升）或低于（突降或步降）输入电源的输出电源电压。其他拓扑结构可能包括：降压-升压、反激、正激、Cuk、SEPIC、全桥、半桥和推挽式。这些器件不同于需要最小电压并“烧尽”多余电压的线性稳压器。

description

The 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.
