General DescriptionThe LM2675 seriesof regulators are monolithic integrated
circuits built witha LMDMOS process. These regulators
provideall the active functions fora step-down (buck)
switching regulator, capableof drivinga1A load current with
excellent line and load regulation. These devices are avail-
ablein fixed output voltagesof 3.3V, 5.0V, 12V, andan
adjustable output version.
Requiringa minimum numberof external components, these
regulators are simpleto use and include patented internal
frequency compensation (Patent Nos. 5,382,918 and
5,514,947) anda fixed frequency oscillator.
The LM2675 series operatesata switching frequencyof
260 kHz, thus allowing smaller sized filter components than
what wouldbe needed with lower frequency switching regu-
lators. Becauseofits very high efficiency (>90%),the cop-
per traceson the printed circuit board are the only heat
sinking needed. familyof standard inductorsfor use withthe LM2675 are
available from several different manufacturers. This feature
greatly simplifies the designof switch-mode power supplies
using these advanced ICs. Also includedin the datasheet
are selector guidesfor diodes and capacitors designedto
workin switch-mode power supplies.
Other features includea guaranteed ±1.5% toleranceon
output voltage within specified input voltages and output
load conditions, and ±10%on the oscillator frequency. Ex-
ternal shutdownis included, featuring typically 50 µA
stand-by current. The output switch includes current limiting, wellas thermal shutdownforfull protection under fault
conditions. simplify the LM2675 buck regulator design procedure,
