The LMZ23603TZX/NOPB SIMPLE SWITCHER power module is an easy-to-use step-down DC-DC solution capable of driving up to 3-A load. The LMZ23603TZX/NOPB is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.
The LMZ23603TZX/NOPB can accept an input voltage rail between 6 V and 36 V and deliver an adjustable and highly accurate output voltage as low as 0.8 V. The LMZ23603TZX/NOPB only requires two external resistors and three external capacitors to complete the power solution. The LMZ23603TZX/NOPB is a reliable and robust design with the following protection features: thermal shutdown, programmable input undervoltage lockout, output overvoltage protection, short circuit protection, output current limit, and allows start-up into a prebiased output. The sync input allows synchronization over the 650-kHz to 950-kHz switching frequency range.
