The LMZ12002TZX-ADJ/NOPB SIMPLE SWITCHER? power module is an easy-to-use step-down DC-DC solution capable of driving up to 2-A load with exceptional power conversion efficiency, line and load regulation, and output accuracy. The LMZ12002TZX-ADJ/NOPB is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.
The LMZ12002TZX-ADJ/NOPB can accept an input voltage rail between 4.5 V and 20 V, and can deliver an adjustable and highly accurate output voltage as low as 0.8 V. The LMZ12002TZX-ADJ/NOPB only requires three external resistors and four external capacitors to complete the power solution. The LMZ12002TZX-ADJ/NOPB is a reliable and robust design with the following protection features: thermal shutdown, input undervoltage lockout, output overvoltage protection, short circuit protection, output current limit, and the device allows start-up into a prebiased output. A single resistor adjusts the switching frequency up to 1 MHz.
