Introduction
Power dissipation is a significant problem facing the
designers of DC/DC converters in industrial and automotive applications, where high currents are required,
but space is limited. It is possible to produce a highly
efficient regulator from high performance discrete
components, but expense and solution footprint make
this approach prohibitive. The LT8612/LT8613 high
efficiency buck regulators integrate all the necessary
components into a single IC, significantly reducing
the DC/DC converter size, even when faced with high
step-down ratios. These devices can also be paralleled
to increase the output current capability and spread
the load and heat. high efficiency power switches allows these switches,
the boost diode, internal compensation and all necessary circuitry to be encapsulated in a tiny 3mm Г— 6mm
QFN package without overheating. Figure 1 shows a
typical 5V/30W LT8612 converter; its efficiency and
power loss are demonstrated in Figure 2. Even with
an input voltage of 24V, the LT8612 can produce a
30W output with no more than 50В°C temperature rise. …

Ying Cheng Power dissipation is a significant problem facing the designers of DC/DC converters
in industrial and automotive applications, where high currents are required, but space
is limited. It is possible to produce a highly efficient regulator from high performance
discrete components, but expense and solution footprint make this approach
prohibitive. The LT8612/LT8613 high efficiency buck regulators integrate all the
necessary components into a single IC, significantly reducing the DC/DC converter
size, even when faced with high step-down ratios. These devices can also be
paralleled to increase the output current capability and spread the load and heat.
Other desirable features included in these
regulators are ultralow quiescent current
to maximize battery life, and high switching frequency to minimize solution size
and avoid noise-sensitive frequency bands. Figure 2. Even with an input voltage
of 24V, the LT8612 can produce a 30W
output with no more than 50В°C temperature rise. At the other end of the load
spectrum, the LT8612/LT8613 uses low
ripple Burst ModeВ® operation to enhance
efficiency in ultralow load situations. HIGHLY EFFICIENT 42V, 6A
REGULATORS IN
3mm Г— 6mm PACKAGE The minimum on-times of LT8612/
LT8613 are as low as 40ns, allowing
for high VIN/VOUT ratios even at high …
