RT6316BGQUF集成電路（IC）的線性穩(wěn)壓器控制器規(guī)格書PDF中文資料

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.
