LTM4613IV#PBF Non-Isolated PoL Module DC DC Converter 1 Output 12V 8A 5V - 36V Input

Description
The LTM®4613 is a complete, ultralow noise, 8A switch mode DC/DC power supply. Included in the package

are the switching controller, power FETs, inductor and all support components. Operating over an input voltage

range of 5V to 36V, the LTM4613 supports an output voltage range of 3.3V to 15V, set by a single external

resistor. 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 onboard input filter and noise cancellation circuits achieve low noise coupling,

thus effectively reducing the electromagnetic interference (EMI)-see Figure 7. Furthermore, the DC/DC µModule®

regulator can be synchronized with an external clock to reduce undesirable frequency harmonics and allow

PolyPhase® operation for high load currents. The LTM4613 is offered in 15mm × 15mm × 4.32mm LGA and

15mm × 15mm × 4.92mm BGA packages. The LTM4613 is available with SnPb (BGA) or RoHS compliant

terminal finish.
