Texas Instruments Regulador de módulos nano LMZ2050x SIMPLE SWITCHER®
Los reguladores de módulos nano LMZ2050x SIMPLE SWITCHER® de Texas Instruments son reductores convertidores de CC-CC síncronos capaces de generar una carga de hasta 2 A desde una entrada de hasta 5,5 V, con una eficiencia y precisión de salida excepcionales en un tamaño de solución muy reducido. Este innovador paquete contiene el regulador y el inductor en un volumen pequeño de 3,5 mm × 3,5 mm × 1,75 mm, con lo que se ahorra espacio en la placa y se elimina el tiempo y los gastos de selección de inductor. El LMZ2050x requiere solo cinco componentes externos y tiene una selección de pines diseñada para proporcionar un diseño de PCB sencillo y óptimo.

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.
