18A, 12V input non-isolated wide-output adjust power module
The PTH12020 series of non-isolated power modules from Texas Instruments offers high performance and a small footprint for powering complex multi-processor digital systems. These modules provide step-down power conversion for up to 18 A of output current from a 12-V input bus voltage. The output voltage can be adjusted using a single resistor, with the W-suffix parts ranging from 1.2 V to 5.5 V and L-suffix parts from 0.8 V to 1.8 V.
Key features include Point-of-Load Alliance (POLA) compatibility, Auto-Track sequencing for simplified supply voltage sequencing, and various protection mechanisms such as output over-current protection and over-temperature protection. The modules also support on/off inhibit, pre-bias startup, and output voltage sense for improved load regulation.
