DESIGN FEATURES 2-Phase Dual Synchronous DC/DC
Controller with Tracking Provides High
Efп¬Ѓciency in a Compact Footprint
by Jason Leonard Introduction
The LTC3736 is a 2-phase dual
synchronous step-down DC/DC
controller that requires few external
components. Its No RSENSE, constant
frequency, current mode architecture
eliminates the need for current sense
resistors and improves efп¬Ѓciency, with-out requiring a Schottky diode. The two
controllers are operated 180 degrees
out of phase, reducing the required
input capacitance and power loss and
noise due to its ESR. A tracking input
allows the second output to track the
п¬Ѓrst output (or another supply) dur-59k 187k VIN

DESIGN FEATURES Dual Switcher with Spread Spectrum
by Jason Leonard
Reduces EMI
Introduction
Switching DC/DC power supplies
are increasingly popular in modern
electronic devices because of their
high efп¬Ѓciency, which reduces heat
dissipation and increases battery run
time. Nevertheless, the rapid switching of current makes them a potential
source of radiated and conducted
electromagnetic interference (EMI).
EMI can cause a variety of problems,
from the relatively benign addition of
noise to a television picture or radio
receiver to the more serious impairment of the operation of electronic
devices in critical applications.
Unfortunately, the amount of EMI
generated, and whether it will produce signiп¬Ѓcant interference, is not
easily quantiп¬Ѓable and is often not
known until the late stages of the
development. Therefore, it is wise to
proactively minimize the potential …
