LM2747 Datasheet (National Semiconductor) - Synchronous Buck Controller

LM2747, Synchronous Buck Controller

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 a

LM2747 Features

* 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 fre
