Texas Instruments  LMZ22008TZ/NOPB

The LMZ22008 SIMPLE SWITCHER® power module is an easy-to-use step-down DC-DC solution capable of driving up to 8-A load. The LMZ22008 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.

The LMZ22008 can accept an input voltage rail between 6 V and 20 V and deliver an adjustable and highly accurate output voltage as low as 0.8 V. The LMZ22008 only requires two external resistors and external capacitors to complete the power solution.

The LMZ22008 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 allows start-up into a prebiased 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.
