The SMB122 and SMB122X are highly integrated and flexible eight channel power managers 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 SMB122 and SMB122X integrate all the essential blocks required to implement a complete eight-channel power subsystem including three synchronous step-down "Buck" converters, one configurable step-up "Boost" or step-down synchronous "Buck" converter, two step-up (Boost) converters, one configurable step-up "Boost" or inverting step-up/down "Buck-Boost" converter, one linear regulator (LDO) and a fully programmable Li-Ion battery charger.
