SMB120 Datasheet PDF - Summit Microelectronics

INTRODUCTION
   The SMB120 is a highly integrated and flexible nine-channel programmable 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. Complete with a user friendly GUI, all programmable settings including output voltages and input/output voltage monitoring can be customized with ease.
