INTRODUCTION

The SMB20X/20XA are a highly integrated and flexible Single/Dual-output DC-DC regulator designed for use in a wide variety of applications. High integration reduces system cost, component count and development time while the built-in non- volatile digital programmability allows system designers to custom tailor the device to suit almost any application.

The SMB20X/20XA include single/dual DC-DC step-down regulators with integrated high-side MOSFET switches for up to 1A/2A/4A continuous output current. Programmable output voltages as low as +0.8V support the latest VLSI digital cores. Minimum external components result in a very compact solution size for space constrained applications.
