LM2747 Synchronous Buck Controller with Pre-bias Startup, and Optional Clock Synchronization
General Description
The LM2747 is a high-speed synchronous buck regulator controller with a feedback
voltage accuracy of ± 1%.
It can provide simple down conversion to output
voltages as low as 0.
6V.
Though the control section of the IC is rated for 3 to 6V, the driver section is designed to accept input supply rails as high as 14V.
The use of adaptive non-overlapping
MOSFET gate drivers helps avoid potential shoot-through problems while maintaining high efficiency.
The IC is...
