DescriptionThe LMZ14203TZX-ADJ/NOPB SIMPLE SWITCHER power module is an easy-to-use step-down DC-DC solution thatcan drive up to 3-A load with exceptional power conversion efficiency, line and load regulation,and output accuracy. The LMZ14203TZX-ADJ/NOPB is available in an innovative package that enhances thermalperformance and allows for hand or machine soldering.
The LMZ14203TZX-ADJ/NOPB can accept an input voltage rail between 6 V and 42 V and deliver anadjustable and highly accurate output voltage as low as 0.8 V. The LMZ14203TZX-ADJ/NOPB only requires threeexternal resistors and four external capacitors to complete the power solution. The LMZ14203TZX-ADJ/NOPB is areliable and robust design with the following protection features: thermal shutdown, input UVLO,output overvoltage protection, short-circuit protection, output current limit, and allows start-upinto a prebiased output. A single resistor adjusts the switching frequency up to 1 MHz.
