Datasheet Details

Part number	LM2747
Manufacturer	National Semiconductor
File Size	1.01 MB
Description	Synchronous Buck Controller
Datasheet	LM2747_NationalSemiconductor.pdf

The LM2747 is a high-speed synchronous buck regulator controller with a feedback voltage accuracy of ± 1%.

a fixed-frequency voltage-mode PWM control architecture which is adjustable from 50 kHz to 1 MHz with one external resistor. In addition, the LM2747 also allows the switching frequency to be synchronized to an external clock signal over the range of 250 kHz to 1 MHz. This wide range of switching frequency gives the power supply designer the flexibility to make better tradeoffs between component size, cost and efficiency. Features include the ability to startup with a pre-biased load on the outpu.
