High-Current POL Converters Designed for Space-Critical Blade Server and Communications Applications

Power-One introduces three new high-current Point-of-Load (POL) converters.

These 40, 50, and 60 amp non-isolated DC-DC converters utilize multiphase-synchronous-buck topologies to deliver up to 93% efficiencies in high-power-density packages designed for space-critical blade server and communications applications.

Wide input ranges (5 – 13.8V) combined with user-defined outputs (0.6 – 3.6V) significantly reduce the number of model numbers required in inventory. Advanced thermal-management techniques facilitate a 0 to 70 ēC operating range with best-in-class elevated-temperature performance. Additional features include: tightly regulated outputs, no minimum load requirements, the capability to start up into pre-biased loads, and low-noise fixed-frequency operation.

Protections include overcurrent, output overvoltage, and overtemperature with automatic restart. Interface capabilities include Power Good signals and Enable inputs. Safety agency approvals include: UL60950, CSA C22.2 No. 60950-00, TUV EN60950-1:2001, and UL94 V-0 flammability ratings.

The 40-amp, horizontal-mount YH09T40 utilizes an industry-standard 1.45” x 1.115” (36.83mm x 28.32mm) footprint and a 0.5” (12.7mm) height. A data sheet is available at: http://www.power-one.com/resources/products/datasheet/yh09t40_v2.pdf

The 50-amp, vertical-mount YV09T50 utilizes an industry-standard 1.45 x 0.725” (36.83mm x 18.41mm) SIP footprint and a 1.115” (28.32mm) height. A data sheet is available at: http://www.power-one.com/resources/products/datasheet/yv09t50_v1.pdf

The 60-amp, vertical-mount YV09T60 utilizes an industry-standard 2.58” x 0.628” (65.5mm x 16mm) SIP footprint, and a 1.25” (31.8mm) height. A data sheet is available at: http://www.power-one.com/resources/products/datasheet/yv09t60_v3.pdf
