ADI's ADP2441 is a constant frequency, current-mode control, synchronous step-down DC-to-DC regulator that is capable of driving loads up to 1 A with excellent line and load regulation characteristics. The ADP2441 operates with a wide input voltage range of 4.5 V to 36 V, which makes it ideal for regulating power from a wide variety of sources. In addition, the ADP2441 has very low minimum on time (50 ns) and is, therefore, suitable for applications requiring a very high step-down ratio.
The output voltage can be adjusted from 0.6 V to 0.9 V x VIN. High efficiency is obtained with integrated low resistance N-channel MOSFETs for both high and low-side devices.
