The LMZ12008 SIMPLE SWITCHER® power module is an easy-to-use step-down DC-DC solution capable of driving up to 8-A load. The LMZ12008 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.
The LMZ12008 can accept an input voltage rail between 6 V and 20 V and can deliver an adjustable and highly accurate output voltage as low as 0.8 V. The LMZ12008 only requires two external resistors and external capacitors to complete the power solution. The LMZ12008 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.
