SMB214A(2008) Datasheet PDF - Summit Microelectronics

INTRODUCTION
   The SMB214A/B/C are highly integrated and flexible threechannel power managers designed for use in a wide range of applications. The built-in digital programmability allows system designers to custom tailor the device to suit almost any multichannel power supply application from digital camcorders to set-top boxes. Complete with a user friendly GUI, all programmable settings, including output voltages and input/output voltage monitoring, can be customized with ease.
