3 Description
The LMZ12003 SIMPLE SWITCHER® power module is an easy-to-use step-down DC-DC solution capable
of driving up to 3-A load with exceptional power
conversion efficiency, line and load regulation, and
output accuracy. The LMZ12003 is available in an
innovative package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ12003 can accept an input voltage rail
between 4.5 V and 20 V and can deliver an
adjustable and highly accurate output voltage as low
as 0.8 V. The LMZ12003 only requires three external
resistors and four external capacitors to complete the
power solution. The LMZ12003 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 this device allows start-up into a
prebiased output. A single resistor adjusts the
switching frequency up to 1 MHz.
