Keywords:LMZ12003? Simple Switcher? thermal performance?

The LMZ12003 Simple Switcher power module is a step-down DC-DC solution capable of driving up to 3A load. The LMZ12003 is available in a package that is touted to enhance thermal performance and allows for hand or machine soldering.

The LMZ12003 demo board can accept an input voltage rail between 4.5V and 20V and deliver an adjustable and highly accurate output voltage as low as 0.8V. The LMZ12003 only requires three external resistors and four external capacitors to complete the power solution. The LMZ12003 is a solution with the following protection features: thermal shutdown, input under-voltage lockout, output overvoltage protection, short-circuit protection, output current limit, and allows startup into a pre-biased output. A single resistor adjusts switching frequency up to 1 MHz.
