Reference Designs
Platinum Rated 720W AC/DC Reference Design
This reference design demonstrates the
flexibility and power of dsPIC Digital Signal
Controllers in switch-mode power supplies.
This reference design has a peak efficiency
of 94.1% and achieves the ENERGY STAR
CSCI Platinum Level. It features a 2-phase
interleaved power factor correction boost converter followed
by a 2-phase interleaved two-switch forward converter with
synchronous rectification.
Quarter Brick DC/DC Converter Reference Design
This reference design provides an easy
method to evaluate the performance,
and features of SMPS DSCs in high
density quarter brick DC-DC converters
for Intermediate Bus Architectures
(IBA). This reference design is implemented using a
single dsPIC33F “GS” digital power DSC that provides full
digital control of the power conversion as well as system
management functions.
DC/DC LLC Resonant Converter Reference Design
This reference design operates over a
wide input voltage range (350-420V DC)
with a nominal input of 400V, providing
a 12V DC output, while maintaining
high-voltage isolation between the
primary and secondary. This reference
design is implemented using a single dsPIC33F “GS”
digital power DSC that provides full digital control of the
power conversion and system management functions.
Digital Power Interleaved PFC Reference Design
High performance power supplies are
used in a wide variety of applications
ranging from telecommunication
equipment, industrial equipment, digital
televisions, lighting, air conditioners and
other home appliances. They all need solutions for power
factor correction to improve overall efficiency, improve the
input power factor, voltage regulation and Total Harmonic
Distortion (THD) of the input current.
Digital Pure Sine Wave Uninterruptible Power Supply
(UPS) Reference Design
This reference design demonstrates
how digital power techniques when
applied to UPS applications enable easy
modifications through software, the use
of smaller magnetics, intelligent battery
charging, higher efficiency, compact designs, reduction in
audible and electrical noise via a purer sine-wave output,
USB communication and low-cost overall bill-of-materials.
Grid Connected Solar Micro Inverter
Reference Design
This reference design ensures maximum
power point tracking for PV panel
voltages between 20V to 45V DC and has
a maximum output power of 215 Watts.
High efficiency was achieved by implementing a novel
interleaved active-clamp flyback topology with Zero Voltage
Switching (ZVS). dsPIC33F ‘GS’ devices enable designers
to easily and cost effectively develop products using
advanced switching techniques/topologies that lower
switching losses and improve overall system efficiency.
Two versions of this design are available to support 120V
and 230V grids

Development Boards
MPLAB®Starter Kit for Digital Power (DM330017)
This Starter Kit allows the user to
easily explore the capabilities and
features of the dsPIC33F GS Digital
Power Conversion family. It is a digitally
controlled power supply board that
consists of one independent DC/DC synchronous Buck
converter and one independent DC/DC Boost converter.
Each power stage includes a MOSFET controlled 5W
resistive load. The starter kit includes an On-Board
Debugger/Programmer.
Digital LED Lighting Development Kit (DM330014)
This LED lighting development kit
enables designers to quickly leverage
the capabilities and performance of the
dsPIC33 ‘GS’ DSCs to create a 100%
digitally controlled ballast function, while
including advanced features such as
dimming and color hue control. The dsPIC33 ‘GS’ devices
can support an entire system implementation for LED
lighting products, including power-conversion circuits, such
as AC-to-DC and DC-to-DC conversion, along with functions
such as Power Factor Correction (PFC).
Buck/Boost Converter PICtail Plus Card (AC164133)
A low-cost development platform for
dsPIC33F ‘GS’ devices, the buck/boost
converter PICtail Plus card has two buck
stage outputs and one boost stage
output. Various performance measures
like digital control loop performance of power conversion,
dynamic load performance, multi-phase buck and
synchronous buck converter operation, parallel operation
of two buck converters and multiple output control with a
single dsPIC device can be evaluated. This board can be
used with either the Explorer 16 board or the 16-bit 28-pin
starter board.
