SIMPLIFIED APPLICATIONS DRAWING
The SMB113 is a highly integrated and flexible four-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. Complete with a user friendly GUI, all
programmable
settings
including
input/output voltage monitoring can be customized with ease.
The SMB113 integrates all the essential blocks required to
implement a complete four-channel power subsystem
consisting of four synchronous step-down “buck” controllers.
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,
UV/OV/input/output monitoring on all channels.
The integration of features and built-in flexibility of the SMB113
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
SMB113 this facilitates rapid design cycles and proliferation
from a base design to future generations of product.
The SMB113 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 I
C bus. All user-
programmed settings are stored in non-volatile EEPROM of
which 96 bytes may be used for general-purpose memory
applications. The operating temperature range is 0C to +70C
and the available package is a lead-free, Green, RoHS
compliant, 32-pad QFN-32.
