RT7235/36/39/40
5A, 18V, 650kHz, ACOT® Synchronous Step-Down Converter
General Description
The RT7235/36/39/40 is a synchronous step-down DC/ DC converter with Advanced Constant On-Time (ACOT®) mode control.
It achieves high power density to deliver up to 5A output current from a 4.
5V to 18V input supply.
The proprietary ACOT® 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, RT7235/36/39/40 keeps an excellent constant switching frequency under line and load variation a...
