LMZ22005 (ACTIVE)

5A SIMPLE SWITCHER® Power Module with 20V Maximum Input Voltage

 

Description

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

The LMZ22005 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 LMZ22005 only requires two external resistors and three external capacitors to complete the power solution. 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 950-kHz switching frequency range.
