Nine-Channel DC/DC Digitally Programmable System Power Manager
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.
The SMB120 integrates all the essential blocks required to implement a complete nine-channel power subsystem including four synchronous step-down “buck” controllers, three step-up “boost” controllers, one inverting “buck-boost” controller, and one linear regulator (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, dynamic voltage management and UV/OV/input monitoring on all channels.
The integration of features and built-in flexibility of the SMB120 allows the system designer to create a “platform solution” that can be easily modified via software without major hardware changes.
