20V

The LMZ12002 from Texas Instruments is an easy-to-use SIMPLE SWITCHER power module that functions as a step-down DC-DC converter. It is capable of delivering up to 2A of load current with excellent power conversion efficiency, line, and load regulation.

This power module accepts an input voltage range of 4.5V to 20V and can provide an adjustable output voltage as low as 0.8V, up to a maximum of 6V. It features a maximum total power output of 12W and can achieve efficiencies of up to 92%. The switching frequency can be adjusted up to 1 MHz using a single external resistor.

The LMZ12002 is designed for ease of use, requiring only three external resistors and four external capacitors to complete the power solution. It includes integrated protection features such as thermal shutdown, input under-voltage lockout, output over-voltage protection, short-circuit protection, and output current limiting. The module is housed in an innovative TO-PMOD package, which enhances thermal performance and supports both hand and machine soldering.

Applications for the LMZ12002 include point-of-load conversions from 5V and 12V input rails, time-critical projects, and space-constrained, high thermal requirement applications. Its fast transient response makes it suitable for FPGAs and ASICs.
