The LM2854 PowerWise™ buck regulator
kHzor 1-MHz step-down switching voltage
capableof driving uptoa 4-A load with exceptional
power conversion efficiency, line and load regulation,
and output accuracy. The LM2854 can accept an
input voltage rail between 2.95V and 5.5 V, and
deliver an adjustable and highly accurate output
voltageas lowas 0.8V. Externally established soft-
start witha small capacitor facilitates controlled start-
up, and the LM2854is capableof starting gracefully
intoa 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 limitis usedto
protect the load from an overcurrentor short-circuit
fault, and an enable comparator simplifies
sequencing applications. The LM2854is availablein exposed pad HTSSOP-16 package that enhances
the thermal performanceof the regulator.
