TLVR inductors deliver extremely high current capabilities

Bourns, Inc. has introduced its Model TLVR1005T and TLVR1105T Series. Bourns’ new multiphase TLVR inductors deliver extremely high current capabilities, low inductance, and low DCR and are designed to meet today’s data-driven application performance needs. These types of applications have evolved in processing performance and now need the support of power bead inductors that can match their extremely high current specifications in the same, if not less, board space. The inductors meet these needs for servers, workstations, data centres, storage systems, and desktop computers, as well as in graphics cards and a variety of battery-powered systems.

A problem arises with conventional multiphase VRs in balancing performance, as high-current output demands require an increase in the duty cycle previously handled via long individual-phase stages. New multiphase TLVR architectures, developed to mitigate transient responses stemming from sudden increases in load output, are widely adopted to address these concerns. As such, system designers see the advantages of phase coupling in TLVR architectures, enabling extremely fast transient response, scalable with CPU, FPGA, and ASIC load requirements. Adopting this architecture allows designers to develop robust systems without sacrificing other critical design parameters such as board space, system efficiency, power density, or BOM costs.

Engineered with a dual-winding structure and clip-type coil, the series delivers the low inductance and extremely high current capabilities (Irms up to 77A and Isat up to 160A) needed in a new generation of multiphase power solutions. The series’ shielded construction offers low radiation, with an inductance range of 70nH to 200nH and an operating temperature range of -40C to +125C.

The series is available now and is RoHS-compliant and halogen-free.
