Renesas offers a robust portfolio of PWM controllers engineered for highly efficient DC/DC and AC/DC power supplies that require isolated transformers. With a mix of single- and double-ended isolated controllers and advanced ZVS full-bridge options, our converter product deliver an optimal balance of performance, reliability, and precision for demanding applications like off-line AC/DC systems and telecom-input DC/DC converters.
Our AC/DC solutions feature the smallest packages in the market, making them ideal for space-constrained designs while ensuring powerful performance.
Our unique output current sensing and brick-wall overcurrent protection features safeguard your system by enhancing reliability and stability under heavy workloads.
Innovative full-bridge zero voltage switching (ZVS) control and adjustable dead time management minimize energy loss, boosting the efficiency of power conversion systems.
Designed for diverse use cases, Renesas solutions power AC/DC supplies, brick converters, power factor correction (PFC) boards, and adapters with unmatched scalability and efficiency.
The GaN‑based HWLLC platform delivers 500W and higher performance for IoT, industrial, and infrastructure systems. Its wide input and output range scales an ultra‑efficient, compact architecture from 100W to 500W for lighting, motor control, and next‑generation fast chargers. By avoiding the size, heat, and efficiency limits of legacy designs, it enables smaller 240W USB PD EPR adapters and replaces bulky brick chargers.
This HWLLC‑based AC/DC solution enables designers to move beyond 100W USB‑C adapters and adopt 240W USB PD 3.2 EPR charging for smaller, higher power chargers in smartphones, laptops, and gaming systems. Our compact architecture combines ultra‑low standby power control with advanced Renesas SuperGaN® D‑mode technology to accelerate development of efficient, high‑power‑density adapters.
