Pushes Monolithic Performance Limits
Stephanie Dai Monolithic switching regulators and switching controllers together dominate the DC/DC
converter market. Generally, there is little overlap in their respective applications.
Controller-based solutions are favored for high performance, higher power applications
where minimal power loss and top thermal performance are priorities. In contrast,
monolithic regulators are favored in lower power applications where compact size
is the main requirement. Controllers typically offer more features than monolithic
solutions, but are at a significant solution-size disadvantage. The light footprint of
monolithic regulators usually comes at a cost of features and increased power loss,
and their reliance on integrated MOSFETs places practical limits on power.
The LTC3613 monolithic regulator
blurs the line drawn between applications for controllers and monolithic
regulators by combining a high performance fully featured controller
with onboard low RDS(ON) MOSFETs.
FEATURES The LTC3613 can accept an input voltage between 4.5V to 24V and supports
output voltages between 0.6V to 5.5V. The
onboard top and bottom MOSFETs feature low RDS(ON), around 7mО© and 5mО©,
respectively, keeping power dissipation
low and allowing the LTC3613 to deliver
up to 15A of adjustable load current.
The LTC3613 features true remote differential output voltage sensing. This allows
for accurate regulation of the output …
