GENERAL DESCRIPTION
The
evaluation board is a complete, dc-to-dc switch-
ing regulator design based on the
, a configurable, 1 A,
synchronous step-down, dc-to-dc regulator.
The
The
is a synchronous, step-down dc-to-dc switching
regulator that uses a current mode pulse-width modulation
(PWM) control scheme at medium-to-heavy load currents for
high efficiency and smoothly transitions to a pulse skip mode
at light loads to conserve power. The power switch and
synchronous rectifier are integrated for minimal external part
count and high efficiency. The

is optimized for
operation with small ferrite core inductors and ceramic
capacitors to deliver the maximum output power per square

The
is available with 5 V at 1 A output,
switching frequency set to 500 kHz. If needed, the
evaluation board configuration can be modified by changing
the values of the appropriate passive components.
