The LTM®4613 is a complete, ultralow noise, 8A switch n
EN55022 Class B Compliant
mode DC/DC power supply. Included in the package are the n
Wide Input Voltage Range: 5V to 36V
switching controller, power FETs, inductor and all support n
8A Output Current
components. Operating over an input voltage range of 5V n
3.3V to 15V Output Voltage Range
to 36V, the LTM4613 supports an output voltage range of n
Low Input and Output Referred Noise
3.3V to 15V, set by a single external resistor. Only bulk n
Output Voltage Tracking and Margining
input and output capacitors are needed to finish the design. n
PLL Frequency Synchronization
High switching frequency and an adaptive on-time current n
2% Maximum Total DC Error
mode architecture enables a very fast transient response n
Power Good Tracks with Margining
to line and load changes without sacrificing stability. n
Current Foldback Protection
n
Parallel/Current Sharing
The onboard input filter and noise cancellation circuits n Ultrafast Transient Response achieve low noise coupling, thus effectively reducing n Current Mode Control the electromagnetic interference (EMI)—see Figure 7. n Programmable Soft-Start Furthermore, the DC/DC µModule® regulator can be syn- n Output Overvoltage Protection chronized with an external clock to reduce undesirable n –55°C to 125°C Operating Temperature Range frequency harmonics and allow PolyPhase® operation for (LTM4613MPV, LTM4613MPY) high load currents. n 15mm × 15mm × 4.32mm LGA and The LTM4613 is offered in 15mm × 15mm × 4.32mm 15mm × 15mm × 4.92mm BGA Packages LGA and 15mm × 15mm × 4.92mm BGA packages.
