overview

1. Purpose

<p class="MsoNormal">The RT6208 is a high voltage Buck converter that can deliver up to 100mA output current from a wide input voltage range of 4.5V to 36V. This document explains the function and use of the RT6208 evaluation board (EVB) and provides information to enable operation and modification of the evaluation board and circuit to suit individual requirements.</p>

2. Introduction

<h3>General Product Information</h3> <p class="bady">The RT6208 is a high-efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 100mA output current from a 4.5V to 36V input supply. It requires only 25µA typical supply current at no load while maintaining output voltage regulation. The RT6208 achieves Boundary Conduction Mode (BCM) operation, low quiescent current and programmable high-side peak current limit, providing high efficiency over a wide range of load currents. It also provides soft-start protection to eliminate input current surge during start-up. The low current (3µA) shutdown mode provides output disconnect, enabling easy power management in battery-powered systems. The RT6208 is available in a SOT-23-6, SOT-23-8 and SOP-8 (Exposed Pad, with power good function) packages.</p>
