The LMZ22005 SIMPLE SWITCHER power converter module is an easy-to-use, step-down, DC-DC design capable of driving up to 5A load. The LMZ22005 is available in a remarkable package that enhances thermal performance and allows for hand or machine soldering.

The LMZ22005 can accept an input voltage rail between 6V and 20V and can deliver an adjustable and highly accurate output voltage as low as 0.8V. The LMZ22005 only requires two external resistors and three external capacitors to complete the power design. The LMZ22005 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. The sync input allows synchronization over the 650 to 950kHz switching frequency range.
