DescriptionThe LMZ10505EXT power module is a complete, easy-to-use, DC-DC solution capable ofdriving up to a 5-A load with exceptional power conversion efficiency, output voltage accuracy,line and load regulation. The LMZ10505EXT is available in an innovative package that enhancesthermal performance and allows for hand or machine soldering.
The LMZ10505EXT can accept an input voltage rail between 2.95 V and 5.5 V and can deliveran adjustable and highly accurate output voltage as low as 0.8 V. 1-MHz fixed-frequency PWMswitching provides a predictable EMI characteristic. Two external compensation components can beadjusted to set the fastest response time, while allowing the option to use ceramic or electrolyticoutput capacitors. Externally programmable soft-start capacitor facilitates controlled start-up.The LMZ10505EXT is a reliable and robust solution with the following features: losslesscycle-by-cycle peak current limit to protect for overcurrent or short-circuit fault, thermalshutdown, input undervoltage lockout, and prebiased start-up. The LMZ10505EXT is also fully-enabledfor WEBENCH? and Power Designertools.
