Simplify's Take

What believers are saying

  • OmniOn opened a Silicon Valley office on April 6, 2026, for AI sales.
  • Philip Zuk now leads AI and data center, sharpening product-market execution.
  • AcBel forecasts OmniOn revenue growth of 20% to 30% in 2026.

What critics are saying

  • AcBel integration pressure persists until OmniOn proves durable standalone growth in 2026.
  • OmniOn still depends on concentrated CSP and telecom wins, exposing revenue swings.
  • If HVDC execution slips, ABB legacy assets become a commodity business by 2027.

What makes OmniOn Power unique

  • Plano-based OmniOn sells telecom, data-center, and industrial power-conversion hardware.
  • Its 2026 OCP Silver membership gives direct access to hyperscale design conversations.
  • The 1.2MW HVDC sidecar rack positions OmniOn for high-density AI clusters.

Omnion Power Expands Dlynx Iiitm Family With 15, 20, And 30-Amp Fplx-Series Dc/Dc Converters

New FPLX-series point-of-load (POL) modules provide design flexibility with compact 10 millimeter (mm) by 10 mm footprints. High efficiency and power density make the FPLX-series DC/DC converters ideal for a wide variety of networking, data center, telecom, and industrial applications.Power density continues to play an essential role in printed circuit board (PCB) design across industries and applications. With increased computing capacity demands to support today’s connected and fast-paced world, board designers are challenged with packing as many value-added features as possible onto ever-shrinking PCBs. To address power density and efficiency challenges, OmniOn PowerTM has added new FPLX-series DC/DC converters to its DLynx IIITM family of non-isolated point-of-load (POL) modules. The new 15-amp (A) FPLX015, 20A FPLX020 and 30A FPLX030 modules feature compact 10 mm by 10 mm footprints and provide power densities of 97 A/in2, 129 A/in2 and 194 A/in2, respectively.
