INTRODUCTION

The SMB119 is a highly integrated and flexible seven-channel power manager designed for use in a wide range of portable applications. The built-in digital programmability allows system designers to custom tailor the device to suit almost any multi-channel power supply application from digital camcorders to mobile phones. The SMB119 integrates all the essential blocks required to implement a complete seven-channel power subsystem including three synchronous step-down “buck” converters, one configurable step-up “boost” or step-down synchronous “buck” converter, two step-up (boost) converters, and one linear regulator (LDO).
