Texas Instruments TLVM13660EVM Power Module Evaluation Module

Texas Instruments TLVM13660EVM Power Module Evaluation Module (EVM) is designed to showcase the performance of the TLVM13660 36V, 6A synchronous buck DC/DC buck power module. The evaluation module operates over a wide input voltage range of 3V to 36V to deliver a fixed 5V output with better than 1% setpoint accuracy and up to 6A output current. The Texas Instruments TLVM13660 offers an advanced package and pinout design for improved EMI performance, high efficiency, and high reliability. Several features to ensure the protection of the regulator during fault conditions include undervoltage lockout (UVLO), internal soft-start, hiccup-mode overcurrent protection (OCP), and thermal shutdown. An open-drain PGOOD indicator, precision enable, external bias option, RT-adjustable switching frequency, and inverting buck-boost capability are also available.

Features

  • Wide input voltage range of 3V to 36V
  • 5V default output voltage (jumper adjustable to 1.2V, 1.8V, 2.5V, or 3.3V)
  • Output current up to 6A 1MHz default switching frequency (jumper adjustable to 500kHz, 600kHz, 750kHz, 800kHz, or 1MHz)
  • Input EMI filter included to pass CISPR 32 Class B conducted emissions
  • Fully assembled, tested, and proven PCB layout with a small solution footprint

Required Equipment

  • Voltage Source
    • The input voltage source VIN should be a 36V variable DC source capable of supplying 6A
  • Multimeters
    • Voltmeter 1
      • Measure the input voltage at VIN S+ to VIN S–
    • Voltmeter 2
      • Measure the output voltage at VOUT S+ to VOUT S–
    • Ammeter 1
      • Measure the input current
      • Set the ammeter to a 1-second aperture time
    • Ammeter 2
      • Measure the output current
      • Set the ammeter to a 1-second aperture time
  • Electronic Load
    • Use an electronic load set to constant-resistance (CR) or constant-current (CC) mode and capable of 0ADC to 6ADC
    • For a no-load input current measurement, disconnect the electronic load as it can draw a small residual current
  • Oscilloscope
    • With the scope set to 20MHz bandwidth and AC coupling, measure the output voltage ripple directly across an output capacitor with a short ground lead normally provided with the scope probe
    • Place the oscilloscope probe tip on the positive terminal of the output capacitor, holding the ground barrel of the probe through the ground lead to the negative terminal of the capacitor
    • TI does not recommend using a long-leaded ground connection because this may induce additional noise given a large ground loop
    • To measure other waveforms, adjust the oscilloscope as needed
