Description

General part information

LMZ12003 Series

The LMZ12003EXT SIMPLE SWITCHER®power module is an easy-to-use step-down DC-DC solution capable of driving up to 3-A load with exceptional power conversion efficiency, line and load regulation, and output accuracy. The LMZ12003EXT is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.

The LMZ12003EXT 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 LMZ12003EXT only requires three external resistors and four external capacitors to complete the power solution. The LMZ12003EXT 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.
