STEVAL-ISA028V1 Single phase 20 A step-down converter evaluation board based on the L6727 Data Brief Features BOM optimized for 12 V input / 1.25 V output 20 A High flexibility to host wide range designs Customizable output voltage L6726A / L6727 compatibility Controller input voltage (V ) range from 5 V to CC 12 V Conversion input voltage (V ) up to 13.2 V IN DPAK / SO-8 / PowerSO-8 / PowerFLAT MOSFET compatibility Multi-footprint for input and output capacitors Through-hole / SMD inductor compatibility 4-layer PCB STEVAL-ISA028V1 Description This evaluation board demonstrates the key features of STMicroelectronics L6727, a new powerful new buck controller. The L6727 makes the design of complete step-down voltage regulators simple and cost effective. It provides a full solution by integrating a 0.8 V reference, control logic and protection, and NMOS drivers in an 8-pin package. The L6727 evaluation board implements a step-down DC/DC converter in a four-layer PCB and demonstrates the operation of the device in a general-purpose application. The input voltage can range from 5 V to 12 V and the output voltage is fixed at 1.25 V. The application can deliver an output current up to 20 A. Airflow must be applied with current higher than 18 A ( V = 5 V). The switching frequency is 300 kHz.
