Texas Instruments LMR140x0SEVM/LMR140x0QDPREVM Evaluation Modules
Texas Instruments LMR140x0SEVM/LMR140x0QDPREVM Step-Down Regulator Evaluation Modules (EVMs) are fully assembled and tested circuits for evaluating the LMR140x0 series step-down converters. The LMR140x evaluation modules operate from 7V to 40V input voltage range. Each evaluation module provides a 5V or 3.3V output at either 2A (LMR14020), 3.5A (LMR14030), or 5A (LMR14050). The board has jumper connectors to enable or disable the converter operation, change the output voltage, and synchronize to an external clock. The Texas Instruments LMR140x0SEVM/LMR140x0QDPREVM also has AC signal injection terminals for feedback loop measurements.
Features
- 7V to 40V input voltage range
- Jump selectable output options (5.0V to 3.3V)
- Up to 2A output current
- Switching frequency of 1.6MHz
- Internal compensation (LMR140x0QDPREVM only)
