| INTRODUCTION |
|
The SMB119 is a highly integrated and flexible seven-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 multi-channel power supply application from digital camcorders to mobile phones.
The SMB119 integrates all the essential blocks required to implement a complete seven-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, and one linear regulator (LDO).
Additionally sophisticated power control/monitoring functions required by complex systems are built-in. These include digitally programmable output voltage setpoint, power-up/down sequencing, enable/disable, margining, dynamic voltage management, and UV/OV input/output monitoring on all channels. By incorporating a second ENABLE input and 7-level dynamic voltage control, the SMB119 is ideal for powering systems based on Xscale™ and other similar processors.
The integration of features and built-in flexibility of the SMB119 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 SMB119, this facilitates rapid design cycles and proliferation from a base design to futures generations of product.
The SMB119 is suited to battery-powered applications with an input range of +2.7V to +6.0V and provides a very accurate voltage regulation (<1.5%). Communication is accomplished via the industry standard I2C bus. All user-programmed settings are stored in nonvolatile EEPROM of which 96 bytes may be used for general-purpose memory applications. The commercial operating temperature range is 0C to +70C, the industrial operating range is –40C to +85C, and the available package is a 48-pad 7mm x 7mm QFN.

“The SMB119’s digital power control functionality and operational versatility deliver high performance and flexibility. At the same time, the device’s high efficiency meets Summit’s commitment to offer ‘green’ systems solutions.”
- George Paparrizos, Summit marketing director.
