Texas Instruments Regolatore modulo nano LMZ2050x SIMPLE SWITCHER®

I regolatori modulo nano LMZ2050x SIMPLE SWITCHER® di Texas Instruments sono convertitori CC-CC step-down sincroni facili da utilizzare in grado di pilotare fino a 2 A di carico da un ingresso fino a 5,5 V, con eccezionale efficienza e precisione di uscita in una soluzione di piccole dimensioni. Il package innovativo contiene il regolatore e l'induttore in un piccolo volume di 3,5 mm × 3,5 mm × 1,75 mm, per un risparmio di spazio sulla scheda e per eliminare tempo e costi nella selezione dell'induttore. LMZ2050x richiede solo 5 componenti esterni e dispone di una piedinatura progettata per un layout della PCB semplice e ottimale.

LMZ2050xEVM Eval Modules

Texas Instruments LMZ2050xEVM Evaluation Modules are capable of driving up to 2A load with excellent power conversion efficiency, output voltage accuracy, line and load regulation and load transient response. Each evaluation board is configured for 1.8V output voltage from 2.375V to 5.5V (LMZ20501EVM) or 2.7V to 5.5V (LMZ20502EVM) input, based on the resistor voltage divider RFBT and RFBB. Each board has a double sided six pin connector and turret terminals for easy connection and input supply, ground and load. The board features: three pin jumpers for EN, mode and frequency response analyses, power good monitoring when connected to a rail, inductor current sensing using a wire loop across the multilayer vias before the output capacitors, jumper option for mode pin to run the part on PFM or PWM at light load, frequency response jumper to measure the response across injection voltage resistor and the enable jumper to measure the quiescent current of the module.
