DescriptionThe LMZ10503EXT power module is a complete, easy-to-use, DC-DC solution capable ofdriving up to a 3-A load with exceptional power conversion efficiency, output voltage accuracy,line and load regulation. The LMZ10503EXT is available in an innovative package that enhancesthermal performance and allows for hand or machine soldering.
The LMZ10503EXT accepts an input voltage rail between 2.95 V and 5.5 V and delivers anadjustable and highly accurate output voltage as low as 0.8 V. 1-MHz fixed-frequency PWM switchingprovides a predictable EMI characteristic. Two external compensation components can be adjusted toset the fastest response time, while allowing the option to use ceramic or electrolytic outputcapacitors. Externally programmable soft-start capacitor facilitates controlled start-up. TheLMZ10503EXT is a reliable and robust solution with the following features: lossless cycle-by-cyclepeak current limit to protect for over current or short-circuit fault, thermal shutdown, inputundervoltage lockout, and prebiased start-up. The LMZ10503EXT is also fully-enabled forWEBENCH? and Power Designertools.
