Description
STEVAL-ISA027V1
The purpose of this design is to demonstrate the
key features of STMicroelectronics' L6726A, a
new powerful new buck controller. The L6726A
allows the simple and cost effective design of
complete step-down voltage regulators. Indeed,
and provides a full solution by integrating an 0.8 V
reference, control logic and protection, and NMOS
drivers in an 8-pin package. Moreover, it features
a simple control loop with transconductance error
amplifier and soft-start programmability. The
L6726A evaluation board implements a step-down
DC-DC converter, in a four-layer PCB, and
demostrates 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, with a switching
frequency of 270 KHz.
