SMB120

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. Complete with a user friendly GUI, all programmable settings including output voltages and input/output voltage monitoring can be customized with ease.

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- oost" controller, and one linear regulator (LDO). Additionally sophisticated power control/monitoring functions required by complex systems are built-in. These include digitally  rogrammable 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. Combined with the re-programmability of the SMB120 this facilitates rapid design cycles and proliferation from a base design to future generations of product.

The SMB120 is suited to battery-powered applications with an input range of 2.7V to 6.0V. Output voltages are extremely accurate (<0.5%) employing proprietary ADOC™ technology. Communication is via the industry standard I²C bus. All userprogrammed settings are stored in non-volatile EEPROM of which 96 bytes may be used for general-purpose memory applications. The commercial operating temperature range is 0°C to +70°C and the industrial temperature range is 40°C to +85°C The SMB120 is available in a lead-free, RoHS compliant 9mm x 9mm 64 pin QFN package.
