GENERAL DESCRIPTION
The
evaluation board is a complete, dc-to-dc
switching regulator design based on the
, a configurable,
is a synchronous, step-down dc-to-dc switching
regulator that uses a current mode pulse-width modulation
(PWM) control scheme. The
(PWM) control scheme. The
can be configured for
pulse skip mode at light load or forced PWM mode. The power
switch and synchronous rectifier are integrated for minimal
external part count and high efficiency. The
switch and synchronous rectifier are integrated for minimal
external part count and high efficiency. The
optimized for operation with small ferrite core inductors and
ceramic capacitors to deliver the maximum output power per
square millimeter of the printed circuit board (PCB) area.
The
ceramic capacitors to deliver the maximum output power per
square millimeter of the printed circuit board (PCB) area.
The
is available with 5 V at a 1 A output, with
a switching frequency set to 500 kHz. If needed, the
device can be found
in the
data sheet, which is available from Analog
Devices, Inc., and should be consulted in conjunction with this
