The LMZ23605TZX/NOPB SIMPLE SWITCHER power module is an easy-to-use step-down DC – DC solution capable of driving up to 5-A load. The LMZ23605TZX/NOPB is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.
The LMZ23605TZX/NOPB can accept an input voltage rail between 6 V and 36 V and can deliver an adjustable and highly accurate output voltage as low as 0.8 V. The LMZ23605TZX/NOPB only requires two external resistors and three external capacitors to complete the power solution. The LMZ23605TZX/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 the device allows start-up into a prebiased output. The sync input allows synchronization over the 650- to 950-kHz switching frequency range.
