Overview

® RT7278 3A, 18V, 700kHz ACOTTM Synchronous Step-Down Converter General Description The RT7278 is a synchronous DC/DC step-down converter with Advanced Constant On-Time (ACOTTM) mode control.
It achieves high power density to deliver up to 3A output current from a 4.
5V to 18V input supply.
The proprietary ACOTTM mode offers an optimal transient response over a wide range of loads and all kinds of ceramic capacitors, which allows the device to adopt very low ESR output capacitors for ensuring performance stabilization.
In addition, RT7278 keeps an excellent constant switching frequency under line and load variation and the integrated synchronous power switches with the ACOTTM mode operation ...
