3 Description
The LM5155x-Q1 (LM5155-Q1 and LM51551-Q1) is a
wide input range, non-synchronous boost controller
that uses peak current mode control. The device can
be used in boost, SEPIC, and flyback topologies.
The LM5155x-Q1 can start up from a 1-cell battery
with a minimum of 2.97 V if the BIAS pin is connected
to the VCC pin. It can operate with the input supply
voltage as low as 1.5 V if the BIAS pin is greater than
3.5 V.
LM5155属于集成电路(IC) > PMIC - 稳压器 - DC DC 开关式控制器。美国德州仪器公司制造生产的LM5155DC-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。
