Regulator Efficient Preregulator for Linear Regulators
DescriptionThe LM2672 series of regulators are monolithic
integrated DC-DC converter built witha LMDMOS
process. These regulators provide all the active
functions fora step-down (buck) switching regulator,
capableof drivinga 1-A load current with excellent
line and load regulation. These devices are available fixed output voltagesof 3.3V,5V, 12V, and an
adjustable output version.
Requiring a minimum number of external
components, these regulators are simpleto use and
include patented internal frequency compensation,
fixed frequency oscillator, external shutdown, soft-
start, and frequency synchronization.
The LM2672 series operatesata switching frequency 260 kHz, thus allowing smaller sized filter
components than what is required with lower
frequency switching regulators. Becauseof its very
high efficiency (>90%), the copper traces on the
printed-circuit board are the only heat sinking
required.
