DescriptionThe LMZ10503TZ-ADJ/NOPB power module is a complete, easy-to-use DC-DC solution capable of driving upto a 3-A load with exceptional power conversion efficiency, output voltage accuracy, line and loadregulation. The LMZ10503TZ-ADJ/NOPB is available in an innovative package that enhances thermal performanceand allows for hand or machine soldering.
The LMZ10503TZ-ADJ/NOPB can accept an input voltage rail between 2.95 V and 5.5 V and can deliver anadjustable and highly accurate output voltage as low as 0.8 V. One megahertz 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 and/orelectrolytic output capacitors. Externally programmable soft-start capacitor facilitates controlledstartup. The LMZ10503TZ-ADJ/NOPB is a reliable and robust solution with the following features: losslesscycle-by-cycle peak current limit to protect for over current or short-circuit fault, thermalshutdown, input undervoltage lockout, and prebiased start-up.
