Overview
Description
As electric vehicles (EVs) and hybrid electric vehicles (HEVs) continue to grow, efficient energy transfer between 12V and 48V power nets has become essential for modern vehicle electronics. This compact, high‑efficiency 12V/48V DC/DC converter is well‑suited for 48V mild hybrid electric vehicles (MHEVs) and electric motorcycles. Built around the LV148 48V automotive power‑supply standard used by German automakers, the system supports functional safety requirements and delivers a robust platform for next‑generation dual‑voltage vehicle architectures.
System Benefits:
- Multi‑phase DC/DC system delivers over 3kW between 12V and 48V board nets with efficiency exceeding 95%.
- Simplified control architecture eliminates the need for DSP firmware and separate buck/boost controllers, reducing system complexity, BOM, and time to market.
- Supports ASIL-B automotive safety requirements under ISO 26262 using a Renesas MCU and regulator.
