ROAL Electronics Intros New Sixteenth-Brick DC-DC Converters
ROAL Electronics USA Inc. (Los Angeles, CA), a designer of ac-dc and dc-dc switch-mode power supplies, announced a new fully featured and efficiency-optimized family of 50 W isolated, sixteeenth-brick, dc-dc converters that are suitable for IT, telecommunications and networking applications, and all other applications based on distributed power architectures.
The new product family complements 48 Vdc bus applications for a distributed power architecture concept using point-of-load dc-dc modules. The converters offer a compact board spacing (1.3 in x 0.9 in x 0.35 in) and are compatible with the industry-standard DOSA specifications. The new series operates from a 36 V to 75 V input bus voltage and delivers up to 25 A with the 1.8 V model, 15 A with the 3.3 V model, 10 A with the 5 V model, and 4.12 A from the 12 V model, respectively.
The wide-trim, secondary-side control (-50/+10% for the 1.8 V model; -42/+10% for the 3.3 V model and -20/+10% for the 5 V and 12 V models) makes the converters suitable for multiple and flexible applications, and allows OEM companies to minimize stock. The series also features a fast transient response, a back bias startup of 100% of the set-point voltage, 1.5 kVdc of input-to-output basic insulation.
