TDK-Lambda i9C 1500W DC-DC Buck-Boost Converters with PHEPT
TDK-Lambda i9C 1500W DC-DC Buck-Boost Converters feature Programmable High Efficiency Pass-Through (PHEPT) technology that improves efficiency, reduces thermal stress, and extends battery runtime. The PHEPT technology allows designers to define an input‑voltage window in which the module bypasses regulation and connects the input directly to the output, eliminating switching and conversion losses. TDK-Lambda i9C DC-DC Converters support 9V to 80V or 9V to 40V inputs and 9.6V to 60V or 5V to 36V outputs, delivering up to 1500W for 12V, 24V, 48V, and 60V bus architectures. The i9C comes in a compact, wide quarter‑brick package with a baseplate, enabling flexible cooling options.
The converters feature wide output adjustment, negative logic on/off control, power good, remote sense, user‑adjustable overcurrent protection, low‑power sleep mode, and full auto‑recovery protection. Designed for high‑ambient, low‑airflow environments, the i9C is ideal for industrial, telecom, test and measurement, and battery‑powered applications.
