Pulse continues to expand our portfolio of inductors used to power processors, memory, FPGAs and ASICs in servers, datacenters and storage systems. Our latest product developments are specifically designed for use with the trans-inductor voltage regulator (TLVR) topology and leverage our existing high volume automated manufacturing to ensure quality, reliability, and cost-effectiveness. The TLVR topology enables faster transient response and utilizes a dual winding power bead inductor.
Traditionally, these applications have used single winding inductor used in a multi-phase buck topology which allows currents to be distributed though parallel ‘paths’ or phases. By operating each phase in a staggered fashion, the ripple currents in each phase tend to cancel at the output and the overall ripple current seen at the load is much smaller than the ripple on each phase. This approach allows smaller inductances to be used (typically on the order of 50-300nH) and can allow design engineers a trade-off between how quickly the converter responds to a change in the load current (transient response) verses stability of the control loop. By adjusting the number of phases used in the converter, the designer has flexibility to optimize the circuit for their specific application.
