RT7235GQW

Evaluation Board

Introduction

General Product Information

General Description

The RT7235 is a high-performance 650kHz 5A step down regulator with an internal power switch and synchronous

rectifier. It features quick transient response using its Advanced Constant On-Time (ACOT^TM) control architecture

that provides stable operation with small ceramic output capacitors and without complicated external compensation,

among other benefits. The input voltage range is from 4.5V to 18V and the output is adjustable from 0.765V to 8V.

The proprietary ACOT^TMcontrol improves upon other fast response constant on-time architectures, achieving nearly

constant switching frequency over line, load, and output voltage ranges. Since there is no internal clock, response to

transients is nearly instantaneous and inductor current can ramp quickly to maintain output regulation without large

bulk output capacitance. The RT7235 is stable with and optimized for ceramic output capacitors.

With its internal 90mΩ switch and 60mΩ synchronous rectifier, the RT7235 displays excellent efficiency and good

behavior across a range of applications, especially for low output voltages and low duty cycles. Cycle-by cycle

current limit, input under-voltage lock-out, externally-adjustable soft-start, output under- and overvoltage protection,

and thermal shutdown provide safe and smooth operation in all operating conditions.

The RT7235 evaluation board uses the RT7235GQW IC in a WDFN-10L3x3 package with an exposed thermal pad.

The IC is also available in a PTSSOP-14 package with an exposed thermal pad.
