LTC2912

• Companion module for Active Learning labs on buck and boost power converters
• Illustrates important concepts related to buck and boost converters:
  • Continuous vs. Discontinuous Conduction Modes
  • Open loop operation
  • Voltage mode control
  • Current mode control
• Independently adjustable parameters: frequency, duty cycle, voltage/current mode
• Onboard current sense amplifiers and adjustable load minimize equipment requirements.

The ADALM-SR1 (Analog Devices Active Learning Module, Switching Regulator) board is a companion module for several switching regulator exercises covering buck and boost regulators:

• Boost and Buck converter elements and open-loop operation
• Buck Converters: closed loop operation
• Boost Converters: closed loop operation

The circuits required for these exercises exceed the complexity that can be constructed on a breadboard, so the ADALM-SR1 was designed as a flexible platform for experimenting with power electronics. Onboard current sense amplifiers, adjustable electronic load, and feedback signal injection circuitry eliminate the need for expensive equipment — the only additional equipment required is:

• 5V USB wall adapter
• Basic adjustable power supply for input power (0-12V, 2A)
• Multimeter
• ADALM2000 or basic oscilloscope (2 channels with trigger, >10MHz bandwidth)
