Analog Devices LTM4638IY#PBF Convertisseur CC en CC et module de régulateur de commutation
20VIN, 15A Step-Down DC/DC µModule Regulator
The LTM®4638 is a complete 15A step-down switching mode µModule (power module) regulator in a tiny 6.25mm × 6.25mm × 5.02mm BGA package. Included in the package are the switching controller, power FETs, inductor and support components. Operating over an input voltage range of 3.1V to 20V, the LTM®4638 supports an output voltage range of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers up to 15A continuous output current. Only bulk input and output capacitors are needed.
The LTM®4638 supports selectable discontinuous mode operation and output voltage tracking for supply rail sequencing. Its high switching frequency and current mode control enable a very fast transient response to line and load changes without sacrificing stability.
Fault protection features include overvoltage, overcurrent and overtemperature protection.
The LTM®4638 is available with SnPb or RoHS compliant terminal finish.

Advanced motor control systems improve motor control performance
Electric motors are widely used in various industrial, automotive, and commercial applications. Motors are controlled by drivers, which regulate their torque, speed, and position by altering the input power. High-performance motor drivers can enhance efficiency and enable faster and more precise control. This article introduces modern motor control system architectures and various motor control solutions offered by ADI.
