INFINEON TDM3883 and 3885 IPOL fully integrated single-output buck converters offer a high-efficiency continuous 3A/4A load capability and line regulation over a wide input supply range (4.5 – 14 V). The integrated inductor and capacitors reduce external components and allow easier designs with much higher power density. The integration offers improved performance compared to discrete solutions due to the low parasitic parameters by minimizing the pcb wiring trace needed. Product’s tiny package size permits the modules to fit into the restricted pcb space offering up to 80% area saving.
