Features and Benefits

  • 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.

Product Details

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)

SCP-LT3472-EVALZ

LT3472 Signal Chain Evaluation Board | Dual Boost/Inverting μPower Converter

Buy Now View Details

Product Details

Demonstration circuit SCP-LT3472-EVALZ is a dual output converter featuring the LT3472EDD. The Boost Converter is designed to convert a 2.7V–4.2V input to 15V output at 25mA–45mA load. The Inverting Circuit generates a –8V output at 35mA–65mA from the same input.

Like all boards in the Signal Chain Power series, this board is designed to be easily plugged into other SCP boards to form a complete signal chain power system, enabling fast evaluation of low power signal chains. To evaluate this board, some universal SCP hardware is required, namely:

  • SCP-INPUT-EVALZ
  • SCP-OUTPUT-EVALZ
  • SCP-1X5BKOUT-EVALZ
  • SCP-THRUBRD-EVALZ
  • SCP-FILTER-EVALZ
  • SCP-1X2BKOUT-EVALZ
  • SCP-5X1-EVALZ

 

To properly evaluate SCP series demo boards, you will need the SCP Configurator companion software. SCP Configurator can help you choose the right board and topology for your design.

Note that the Demo Manual does not cover details important to the operation and configuration regarding the LT3472. Please refer to the LT3472 data sheet for a complete description of the part.

LT3472EDD | Boost and Inverting DC/DC Converters, VIN = 2.7V – 4.2V, VOUT1 = 15V @ 25mA–45mA, VOUT2 = –8V @ 35mA–65mA

Product Details

Demonstration circuit 760 is a dual, output, 1.1MHz Boost/Inverter in a 3mm x 3mm DFN featuring the LT3472EDD. The demo circuit demonstrates small size and low component count in a Boost Circuit and an Inverting Circuit. The Boost Converter is designed to convert a 2.7V–4.2V input to 15V output at 25mA– 45mA load. The Inverting Circuit generates a –8V output at 35mA–65mA from the same input. Since the maximum VIN of the LT3472EDD is 16V, this demo circuit will work well at higher inputs. The only limitation is the 10V rating of the input capacitor.
