LM27402SQEVAL
概要
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 setpoint. 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. The LM27402 evaluation board also supports pre-biased startup and provides a tracking connection for power supply sequencing. An external clock can be applied to change the switching frequency through an on board synchronization connection. PGOOD is externally pulled up to VDD and can be monitored via an on board terminal. Two extra terminals are included to provided a network analyzer connection for control loop stability analysis. The PCB measures 1.3? x 1.8? and includes input/output banana connectors for the input supply and load.
