overview

1. Purpose

The RT9088 is a sink/source tracking termination regulator. This document explains the function and use of the RT9088 evaluation board (EVB), and provides information to enable operation, modification of the evaluation board and circuit to suit individual requirements.

2. Introduction

<h3>General Product Information</h3> The RT9088 is a sink/source tracking termination regulator. It is specifically designed for low-cost and low-external component count systems. The RT9088 possesses a high speed operating amplifier that provides fast load transient response and only requires a minimum 30μF ceramic output capacitor. The RT9088 supports remote sensing functions and all features required to power the DDRIII and Low Power DDRIII/DDRIV VTT bus termination according to the JEDEC specification. In addition, the RT9088 provides an open-drain PGOOD signal to monitor the output regulation and an EN signal that can be used to discharge VTT during S3 (suspend to RAM) for DDR applications. The RT9088 is available in the thermal efficient package, WDFN-10L 3x3.

8. Power-up & Measurement Procedure

1. Short J1 and the (1, 2) pin of J2 by jumper respectively. 2. Provide input voltage (2.9V < VCNTL < 5.5V) to VCNTL pin. 3. Connect input power (1.1V < VIN < 3.5V) and input ground to VIN and GND pins respectively. 4. Connect positive end and negative end of load to Vout and GND of output pins respectively. 5. The output voltage of (VOUT) can be set by R1 and R2 : <img alt="" style="width: 161px; height: 45px;" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt9088gqw/html-images/00CB34D2D87343EDB94980F8AE37BCB2_en.ashx" /> 6. If J1 is not shorted by Jumper, the output voltage can be set by the input voltage of REFIN pin : VOUT = VREFIN
