AC164133

AC164133 is a Buck/Boost converter PICtail Plus daughter board that provides an economical development platform for dsPIC® SMPS and digital power conversion GS family DSCs. Buck/boost converter PICtail™ plus board consists of two independent DC/DC synchronous buck converters and one independent DC/DC boost converter. This board can be controlled either by interfacing to 28 - pin Starter Development board or to Explorer 16 Development Board. The control boards provide closed-loop PID control in the software to maintain the desired output voltage level. The dsPIC® SMPS and Power Conversion family devices provide necessary memory and power supply peripherals which enables to build the control loops in software without the need for external circuit. Performance measures that can be evaluated are: digital control loop performance of power conversion, dynamic load performance, multiphase buck and synchronous buck converter, multiple output control with single dsPIC33F GS SMPS device.

• Operates from +9V to +15V DC input
• 3.3V and 5V buck outputs, 20V boost output
• PMBus communication interface connector, 5ohm/5W switchable resistive load - expandable
• Supported by Mindi™ power design and simulator tool
• Parallel operation of two buck converters
• Various fault indication & protection
• Excellent dynamic load performance & output sequencing
• With Explorer 16 use MA330020 (dsPIC33FJ16GS504) or MA330024 (dsPIC33FJ64GS610) Plug-In Module(PIM)
• With 16-bit 28 – pin starter development board use dsPIC33F16GS502-I/SP device
