More Information
The LM2854 PowerWise™ buck regulator is a 500-kHz or 1-MHz step-down switching voltage regulator capable of driving up to a 4-A load with exceptional power conversion efficiency, line and load regulation, and output accuracy. The LM2854 can accept an input voltage rail between 2.95 V and 5.5 V, and deliver an adjustable and highly accurate output voltage as low as 0.8 V. Externally established soft-start with a small capacitor facilitates controlled start-up, and the LM2854 is capable of starting gracefully into a pre-biased output voltage. Partial internal compensation reduces the number of external passive components and PC board space typically necessary in a voltage mode buck converter application, yet preserving flexibility to deal with ceramic and/or electrolytic based load capacitors. Lossless cycle-by-cycle peak current limit is used to protect the load from an overcurrent or short-circuit fault, and an enable comparator simplifies sequencing applications. The LM2854 is available in an exposed pad HTSSOP-16 package that enhances the thermal performance of the regulator.
