LM27402SQEVAL, Evaluation Board using the LM27402 Synchronous, single phase PWM DC/DC Buck Controller
Reference design by: Texas Instruments
LM27402SQEVAL, Evaluation Board using the LM27402 Synchronous, single phase PWM DC/DC Buck Controller. The LM27402 evaluation board represents a 20A typical application circuit. The application circuit is optimized for an input voltage of 12V. However, input voltage feed-forward technology allows the evaluation board to operate up to 20V while maintaining a stable output voltage of 1.5V at 20A. Temperature compensated inductor DCR current limit circuitry provides a steady current limit set point. Extra MOSFET and input/output capacitor footprints are included to accommodate higher currents if desired. An externally set soft-start time of 10 ms provides a controlled monotonic startup
