voltage, by means of a jumper. The frequency is internally
set at 550kHz or can be synchronized with an external
clock. The internal switches allow up to 600mA of output
current in an MSO8 package, providing a space-efficient
solution for battery-powered applications. The DC supply
current is typically only 10µA at no load and less than 1µA
in shutdown. In switching-noise sensitive applications,

operation can be inhibited by grounding the
SYNC/MODE pin with a jumper or synchronizing it with an
external clock.
Gerber files for this circuit board are
available. Call the LTC factory.
DESCRIPTIO
Demonstration circuit DC290 is a constant-frequency
step-down converter using an LTC
®
1877 or an LTC1878
monolithic synchronous regulator. The LTC1878 has an
input voltage range of 2.65V < V
IN
< 6V and the LTC1877
has an input voltage range of 2.65V < V
IN
< 10V. The
LTC1878 is optimized for low voltage operation and is
ideally suited for single Li-Ion cell or 3-NiCd/NiMH cell
applications. The LTC1877, with its higher voltage capa-
bility, is ideally suited for two Li-Ion cells or 4- to 6-NiCd/
NiMH cell applications.
The exclusive use of low profile surface mount compo-
nents on this demo board results in a highly efficient
application in a small volume. The output voltage can be
selected from 1.5V, 2.5V, 3.3V or a user programmable
