3 Description
The LMZ12010 SIMPLE SWITCHER® power module
is an easy-to-use step-down DC-DC solution capable
of driving up to 10-A load. The LMZ12010 is available
in an innovative package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ12010 device 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 LMZ12010 only requires two external resistors
and external capacitors to complete the power
solution. The LMZ12010 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 the device allows start-up
into a prebiased output.
