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.

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 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.
