3 Description
The LM2675 series of regulators are monolithic
integrated DC-DC converter circuits built with a
LMDMOS process. These regulators provide all the
active functions for a step-down (buck) switching
regulator, capable of driving a 1-A load current with
excellent line and load regulation. These devices are
available in fixed output voltages of 3.3 V, 5 V, 12 V,
and an adjustable output version.
Requiring a minimum number of external
components, these regulators are simple to use and
include patented internal frequency compensation
and a fixed frequency oscillator.
The LM2675 series operates at a switching frequency
of 260 kHz, thus allowing smaller-sized filter
components than what would be needed with lower
frequency switching regulators. Because of its very
high efficiency (>90%), the copper traces on the
printed-circuit board are the only heat sinking needed.
