This reference design is a 20 A POL suitable for packaging as a
stand-alone power supply module or can be implemented directly on the
end application circuit board by the OEM. Included in the POL
reference design is a pre-configured software kernel that features
active dynamic dead time control for maximum operating efficiency,
non-linear control response for fast transient response, and SMBus
port capable of supporting industry-standard communication protocols.
The reference design kit is shipped with a complete development
tool suite enabling users to modify the POL application code as
desired. This tool suite consists of a powerful GUI-based application
builder that initializes the switch timing, loop compensation filter
and processor set-up without writing application software. Also
included is an Integrated Development Environment (IDE) that contains
an editor, macro assembler, demo C compiler and a special online
debugger which allows for manual inspection and adjustment of system
parameters during power supply operation.
The POL reference design kit includes full schematics and layout
(Gerber) files that facilitate fast time to market and greatly reduce
design time and effort. The total area occupied by the POL is only 615
mm2 and delivers a maximum of 20 A for a complete 20 A/100 W power
converter. The POL reference design utilizes a 4-layer PCB and is
available with all necessary connectors and switches for complete
evaluation of the product. Also included in the POL is a USB debug
adapter, USB to SMBus communications adapter, USB cable and 2 Ohm load
resistor. The only external hardware required to evaluate the kit is
an external input power supply.
Pricing and Availability
The POL reference design is based on the Si8252 digital power
controller in a 32-pin QFP package. The POL reference design, part
number SINGLEPHSPOL-RD, is now available for $149.
