3 Description
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.
