LM3075
High Efficiency, Synchronous Current Mode Buck
Controller
General Description
The LM3075 is a current mode control, synchronous buck
controller IC. Use of synchronous rectification and pulse-
skipping operation at light load achieves high efficiency over
a wide load range. Fixed frequency operation can be ob-
tained by disabling the pulse-skipping mode. Current mode
control assures excellent line and load regulation and a wide
loop bandwidth for fast response to load transients.
Current mode control can be achieved by either sensing
across the high side NFET or a sense resistor. The switching
frequency can be selected as either 200 kHz or 300 kHz
from an internal clock.
The LM3075 is available with an adjustable output in a
TSSOP-20 package.
