3 Description
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.
