      Applications

The LMZ22010 SIMPLE SWITCHER® power module is an easy-to-use step-down DC-DC solution capable of driving up to 10-A load. The LMZ22010 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.

The LMZ22010 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 LMZ22010 only requires two external resistors and external capacitors to complete the power solution.

The LMZ22010 is a reliable and robust design with the following protection features: thermal shutdown, programmable input under-voltage lockout, output over-voltage protection, short-circuit protection, output current limit, and allows startup into a pre-biased output. The sync input allows synchronization over the 314- to 600-kHz switching frequency range and up to 6 modules can be connected in parallel for higher load currents.
