Lineart launches 10A buck micro module regulator LTM4649

Linear Technology Corporation launches a 10A buckling micro-module (μModule) regulator, which has high work efficiency and low temperature, which uses 9mm x 15mm x 4.92mm BGA (Grid exhibition) Package. At ambient temperature of full power and 0oC to 83oC, the LTM4649 does not require a radiator, airflow or requirement to output current densities, and operates at an efficient efficiency of up to 86% (5VIN ~ 12VIN, 1.5 Vout / 10A). At ambient temperature up to 100oC, the output current only reduces 4A, and only 2A is required in the case of providing 400LFM cooling airflow. The LTM4649 can convert a 4.5V to 16V input power to a lower output voltage (0.6V to 3.3V). The LTM4649 built-in a differential distal sampling amplifier (for compensating the voltage drop caused by the circuit board impedance), which can be adjusted at ± 1.5% accuracy over the entire voltage, load and temperature range (-40oC to 125oC) A load voltage. The LTM4649 provides an input and output clock to implement multiple-phase operations between multiple devices to provide accurate basis for the load of up to 40A. Multiphase operation reduces input and output ripple and reduces the number of inputs and output capacitors. Its applications include load point conversions from 12V or 5V input in telecommunications, industrial, avionics, and test equipment. The LTM4649 can be synchronized to an external clock with a frequency range of 400kHz to 750kHz. With burst mode operations (used to get the highest conversion efficiency under light load) and pulse jump operation (to obtain a lower output voltage ripple) option, the user can realize the individualization of circuit performance. The LTM4649 allows output voltage tracking to complete the sort of multiple power rails in the system. To protect the load, the LTM4649 provides output overvoltage and overcurrent protection. The E-level and I version of the LTM4649 guarantees the internal temperature range of -40oC to 125oC. Overview of performance: LTM4649 10A output current 4.5V to 16V input, 0.6V to 3.3V output No radiator, airflow, or required current drop in ambient temperature of up to 83oC ± 1.5% maximum total DC output voltage error Multi-phase operation and synchronous 9mm x 15mm x 4.92mm BGA package
