dsPICDEM™ SMPS BUCK DEVELOPMENT BOARD KIT
dsPICDEM™ SMPS BUCK DEVELOPMENT BOARD FEATURES
dsPIC DSC SMPS devices are specifically designed to provide low-cost, efficient con-
trol of a wide range of power supply topologies. Their specialized peripherals facilitate
closed-loop feedback control of switched mode power supplies while also providing
communications for remote monitoring and supervisory control.
The dsPICDEM™ SMPS Buck Development Board aids in rapid development of mul-
tiple buck converters using dsPIC30F1010/2020 Digital Signal Controllers. The
dsPIC30F1010/2020 devices offer these features and capabilities:
• Integrated program and data memory on a single chip
• Ultra fast interrupt response time and hardware interrupt priority logic
• 2000 ksps, on-chip ADC with four dedicated sample/hold circuits for multiple loop
• Four independent, high-resolution PWM generators specially designed to support
• Four analog comparators for system protection
• On-chip system communications (I
• On-chip RC oscillator for lower system cost
• High-current sink/source I/O pins: 25 mA/25mA
• 30 MIPS performance CPU
The dsPICDEM™ SMPS Buck Development Board kit contains these items:
• dsPICDEM™ SMPS Buck Development Board
• dsPICDEM™ SMPS Buck Development Board CD containing example code and
The dsPICDEM™ SMPS Buck Development Board incorporates these features:
