RT6316B集成电路（IC）的线性稳压器控制器规格书PDF中文资料

General Description

The RT6316B/C is an advanced constant on-time (ACOT®)

mode synchronous buck converter. The main control loop

of the RT6316B/C using an advanced constant on-time

(ACOT®) mode control which provides a very fast transient

response. The RT6316B operates from 4.5V to 23V input

voltage and RT6316C operates from 5.1V to 23V.

Applications

 Industrial and Commercial Low Power Systems

 Computer Peripherals

 LCD Monitors and TVs

 Green Electronics/Appliances

 Point of Load Regulation for High-Performance DSPs,

FPGAs, and ASICs
