® RT7274/79/80/81 2A, 18V, 700kHz ACOTTM Synchronous Step-Down Converter General Description The RT7274/79/80/81 is a synchronous step-down DC/ DC converter with Advanced Constant On-Time (ACOTTM) mode control.
It achieves high power density to deliver up to 2A 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 capacitor for ensuring performance stabilization.
In addition, RT7274/79/80/81 keeps an excellent constant switching frequency under line and load variation and the integrated synchronous power switches wit...
