LTM4606IY#PBF

LTM4606IY#PBF is a complete, EN55022 Class B certified, high-voltage 6A switching-mode DC/DC power supply. Packaged within are the switching controller, power FETs, inductor, and all necessary support components. The onboard input filter and noise cancellation circuits ensure low-noise operation, effectively reducing electromagnetic interference (EMI). Operating over an input voltage range of 4.5V to 28V, the LTM4606 supports an output voltage range of 0.6V to 5V, which is set by a single resistor. This high-efficiency design delivers 6A continuous current (8A peak). Only bulk input and output capacitors are needed to complete the design. Its high switching frequency and adaptive on-time current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. Applications include ASICs or FPGA transceivers, telecom, servers, and networking equipment, as well as industrial and RF equipment.
