Infineon Technologies TDA38640A Evaluation Board
Infineon TDA38640A Evaluation Board evaluates the performance of the TDA38640A Switching Voltage Regulator IFX POL. The Eval Board is a synchronous buck converter that steps down 12Vin to 1.0Vout. It contains an integrated point-of-load TDA38640A, a fully-integrated and efficient DC-DC regulator. Also onboard is a pulse width modulation (PWM) controller and OPTIMOS FETs with an integrated bootstrap diode. It uses a fast Constant On-Time (COT) control scheme. The Infineon evaluation board provides a small footprint solution with high-efficiency power delivery.
Features
- Soft start
- Thermal protection
- Switching-frequency
- Enable input, output under-voltage lockout
- Over-voltage and over-current protection
- High-side short detection
- Load-line, and pre-bias start-up
- All faults have configurable responses via the available XDP™ Designer GUI from Infineon
- Output over-current protection function is implemented by sensing the voltage developed across the on resistance of the synchronous (low-side) MOSFET for optimum performance
- Current limit is thermally compensated
