Texas Instruments LM5152EVM-BST Controller Evaluation Module

Texas Instruments LM5152EVM-BST Controller Evaluation Module (EVM) showcases the features and performance of the LM5152-Q1 wide input voltage synchronous boost controller. The features include low I_Q operation, internal feedback resistors, bypass mode operation when V_IN is greater than the V_OUT regulation target, and dynamic output voltage tracking. It also includes a STATUS indicator, programmable frequency, clock dithering, and programmable UVLO. The evaluation module is designed to maintain the minimum output of 8.5V at 440kHz during the automotive cranking down to 2.5V boost input. The Texas Instruments LM5152EVM-BST is designed to ease configuration, enabling a user to evaluate the device for an automotive application.

Features

2.5V to 42V input voltage range
Output voltage 8.5V at 34W
440kHz switching frequency

Required Equipment

Power supply
- The input voltage source (V_IN) must be a variable supply with a minimum efficiency of level V
- The power supply must source 2.5V to 36V and be able to supply more than 20A of current
- TI recommends using an external power supply that complies with applicable regional safety standards such as UL, CSA, VDE, or PSE
Electronic load
- Load connected to the output of the evaluation module
- The electronic load must be able to handle up to 36V and dissipate 100W at 8.5V

Multimeters
- For DC measurements
  - Voltmeter 1 (V_IN) is capable of measuring the input voltage range up to 36V
  - Voltmeter 2 (V_OUT) is capable of measuring an output voltage of 36V
  - Ammeter 1 (I_IN) is capable of 20A DC measurement
    - A shunt resistor can also be used to measure the input current
  - Ammeter 2 (I_OUT) is capable of at least 6A DC measurement
