SMB110-Five Channel Programmable DC-DC System Power Manager
INTRODUCTION
The SMB110 is a highly integrated and flexible five-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 multichannel 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.

The SMB110 integrates all the essential blocks required to implement a complete five-channel power subsystem including two synchronous step-down "buck" controllers, one step-up "boost" controller, one inverting "buck-boost" controller and one fixed output +3.3V LDO. Additionally sophisticated power control/monitoring functions required by complex systems are built-in. These include digitally programmable output voltage set point, power-up/down sequencing, enable/disable, margining and UV/OV/input/output monitoring on all channels. The integration of features and built-in flexibility of the SMB110 allows the system designer to create a "platform solution" that can be easily modified via software without major hardware changes.
