Description

The LTM®4612MPV is a complete, ultralow noise, high voltage input and output, 5A switching mode DC/DC power supply. It is designed for use in various applications such as telecom and networking equipment, industrial and avionic equipment, and RF systems.

The LTM4612MPV operates over an input voltage range of 5V to 36V and supports an output voltage range of 3.3V to 15V, set by a single resistor. It is equipped with a switching controller, power FETs, inductor, and all necessary support components. The high switching frequency and adaptive on-time current mode architecture enable a fast transient response to line and load changes without sacrificing stability. Additionally, the onboard input filter and noise cancellation circuits effectively reduce electromagnetic interference (EMI).

The LTM4612MPV can be synchronized with an external clock for reducing undesirable frequency harmonics and allows PolyPhase® operation for high load currents. It is offered in a space-saving and thermally enhanced 15mm × 15mm × 2.8mm LGA package, which optimizes the utilization of unused space on PC boards for high-density point-of-load regulation. The module is also Pb-free and RoHS compliant.
