The SMB110 is a highly integrated and flexible five-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

input/output voltage monitoring can be customized with ease.

The SMB110 integrates all the essential blocks required to

implement a complete five-channel power subsystem including

two synchronous step-down “buck” controllers, one step-up

“boost” controller, one inverting “buck-boost” controller and one

fixed output +3.3V LDO.

control/monitoring functions required by complex systems are

built-in. These include digitally programmable output voltage

set

margining and UV/OV/input/output monitoring on all channels.

The integration of features and built-in flexibility of the SMB110

allows the system designer to create a “platform solution” that

can be easily modified via software without major hardware

changes.

SMB110 this facilitates rapid design cycles and proliferation

from a base design to future generations of product.

The SMB110 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

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.
