LTM4600HVMPV#PBF

LINEAR TECHNOLOGY  LTM4600HVMPV#PBF  芯片, 直流/直流转换器, 10A, 104LGA

The is a high-efficiency DC/DC step down power supply µModule with up to 28V input operation. Operating over an input voltage range of 4.5 to 28V, the LTM4600HV supports an output voltage range of 0.6 to 5V, set by a single resistor. This high efficiency design delivers 10A continuous current, needing no heat sinks or airflow to meet power specifications. Only bulk input and output capacitors are needed to finish the design. High switching frequency and an adaptive on-time current mode architecture enables a very fast transient response to line and load changes without sacrificing stability. Fault protection features include integrated overvoltage and short circuit protection with a defeatable shutdown timer. A built-in soft-start timer is adjustable with a small capacitor.
