DESCRIPTION
The LTC
®
3542-1 is a high efficiency, fixed output voltage
of 2.8V, monolithic synchronous buck converter using a
constant frequency, current mode architecture. Supply
current during operation is only 26μA, dropping to <1μA in
shutdown. The 2.5V to 5.5V input voltage range makes the
LTC3542-1 ideally suited for single Li-Ion battery-powered
applications. 100% duty cycle provides low dropout opera-
tion, extending battery life in portable systems. Internal
power switches are optimized to provide high efficiency
and eliminate the need for an external Schottky diode.
Switching frequency is internally set at 2.25MHz, allowing
the use of small surface mount inductors and capacitors,
and it can synchronize to an external clock signal with a
frequency range of 1MHz to 3MHz through the MODE/SYNC
pin. The LTC3542-1 is specifically designed to work well
with ceramic output capacitors, achieving very low output
voltage ripple and a small PCB footprint.
The LTC3542-1 can be configured for the power saving
Burst Mode
®
Operation. For reduced noise and RF inter-
ference, the MODE/SYNC pin can be configured for pulse
skipping operation.
