LM2745 (LM2745 / LM2748) Synchronous Buck Controller

The LM2745/8 are high-speed synchronous buck regulator controllers with an accurate feedback voltage accuracy of ± 1.5%. It can provide simple down conversion to output voltages as low as 0.6V. Though the control sections of the IC are rated for 3 to 6V, the driver sections are designed to accept in.

LM2745 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 LM2745 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
