- ^O _Description
t(s) ^{This evaluation board demonstrates the key}
c features of STMicroelectronics’ L6727, a new
u _{powerful new buck controller. The L6727 makes}
d _{the design of complete step-down voltage}
ro regulators simple and cost effective. It provides a
P _{full solution by integrating a 0.8 V reference,}
te ^{control logic and protection, and NMOS drivers in}
an 8-pin package. The L6727 evaluation board
le _{implements a step-down DC/DC converter in a}
so ^{four-layer PCB and demonstrates the operation of}
b_{the device in a general-purpose application. The}
Oinput voltage can range from 5 V to 12 V and the
STEVAL-ISA028V1
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_IN = 5 V). The switching frequency is 300 kHz.
