SMB111 Datasheet - Summit Microelectronics

INTRODUCTION
The SMB111 is a highly integrated and flexible four-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. Complete with a user friendly GUI, all programmable settings including output voltages and input/output voltage monitoring can be customized with ease.
