Low IQ Boost Regulator Evaluation Board – LT8365

Overview

Low IQ Boost Regulator Evaluation Board – LT®8365 is a boost converter. It operates with a switching frequency of 400kHz and is designed to convert a 9V to 30V source to 250V, with 10mA output current. The demo board contains an optional third charge pump stage for applications requiring higher output voltages. If needed, remove R14 and install optional components. Output voltage sensing connections remain the same. The LT8365 can be used for different topologies with input voltages up to 60V. However, component selection in this demo circuit restricts the input voltage to 30V.

Capabilities

  1. Conduct live testing of the LT®8365 Boost Converter on real hardware
  2. Perform the following key test evaluations:
    • Operation Mode – Switching waveforms
    • Regulation tests – Line Regulation and Load Regulation
    • Performance tests – Startup transient, Load transient and Efficiency
    • Boundary conditions tests – Input voltage boundary conditions
  3. Observe and analyze waveforms at various test points, such as: 
    • Input voltage
    • Input current 
    • Output voltage
    • Output current
  4. Computed values of regulation and efficiency based on the real-time data are made available to the user.

Features

  • Evaluating the board connected through a real power supply and load system setup. 
  • Exercise all the feature tests with different input and output parameters in real-time.
  • Testing the boundary condition of boost regulator.
