Features
Single phase 5A step-down converter evaluation board
based on L6727
Data Brief
■ Input voltage: from 5V to 12V
■ Output voltage: fixed @ 1.25V but
customizable by changing resistor
■ Output current:up to 5A
t(s) ^{■ Swicthing frequency: 300KHz}
uc _Description
rod ^{The purpose of this design is to demonstrate the}
P ^{key features of STMicroelectronics L6727 a new}
powerful buck controller. The L6727 allow simple,
te _{cost effective design of complete step-down}
le _{voltage regulators. Indeed it provides a full}
o _{solution by integrating a 0.8V reference, control}
bs ^{logic and protection, and NMOS drivers in an 8-}
pin package. L6727 demo board realizes in a two-
- ^{O layer PCB a step-down DC/DC converter and}
) shows the operation of the device in a general-
t(s ^{purpose low-current application. The input voltage}
can range from 5V to 12V buses and the output
uc ^{voltage is fixed at 1.25V. The application can}
d deliver an output current in excess of 5A. The
Obsolete ^{Pro switching frequency is 300 kHz.}
