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.
