The LTM®4606 is a complete EN55022 Class B certified noise high voltage 6A switching mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductor, and all support components. The on-board input filter and noise cancellation circuits achieve low noise operation, thus effectively reducing the 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, set by a single resistor. This high efficiency design delivers 6A continuous current (8A peak). 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. The device supports output voltage tracking and output voltage margining.
Furthermore, the μModule® regulator can be synchronized with an external clock for reducing undesirable frequency harmonics and allows PolyPhase® operation for high load currents.
The LTM4606 is offered in space saving 15mm × 15mm × 2.82mm LGA and 15mm × 15mm × 3.42mm BGA packages. The LTM4606 is available with SnPb (BGA) or RoHS compliant terminal finish.
