1.3.1 Power Stages
• One synchronous Buck converter power stage
• One Boost converter power stage
• Voltage/current measurement and display for digital controlled Buck converter
• Voltage/current measurement and display for digital controlled Boost converter
• MOSFET controlled 5W resistive load on Buck Converter Output (BUCK_Out)
• MOSFET controlled 5W resistive load on Boost Converter Output (BOOST_Out)
1.3.2 Additional Features
• 5 kOhm Potentiometers (P1 and P2), used to adjust the duty cycle of the
load resistors
• On-board temperature sensor, located near the resistive load; this enables the user
to program a temperature protection limit
• Input voltage sense, used to detect under/overvoltage conditions
• Connector for PICkit Serial Analyzer (J3)
• LED power-on indicator (D1)
• LED output voltage indicators (D5 and D12)
• LCD used to display voltage, current, temperature and Fault conditions
1.3.3 Starter Kit Power
• +9V power connector (J2) supplies power to the Digital Power Starter Kit
• USB connection jack (J5) supplies power/connection to the on-board debugger
• Buck and Boost converters are both operated in Voltage mode (default), but can
also be reprogrammed to operate in Average Current or Peak Current Control mode
