The 1,500W non-isolated DC/DC buck-boost power module from TDK-Lambda is designed to maximise system efficiency, reduce thermal stress, and extend battery runtime in demanding industrial and battery-powered applications.
Designated the i9C series it launches with a 9 to 80V input and 9.6 to 60V output model that delivers up to 30A.
A second configuration supporting a 9 to 40V input range with 5 to 36V output and up to 50A is planned to follow, expanding the voltage and current options of the series.
At the core of the i9C series is TDK-Lambda patented programmable high-efficiency pass-through (PHEPT) technology. PHEPT allows designers to define an input voltage window in which the module bypasses regulation and directly connects the input to the output, eliminating switching and conversion losses.
When operating in this mode, efficiency can reach up to 99% which significantly reduces heat generation and improves system reliability for engineers, particularly those designing battery-powered systems.
The converter is packaged in a compact, wide quarter-brick form factor with an integral baseplate that supports convection, conduction, or forced-air cooling, making it well-suited for high-ambient, low-airflow environments.
Standard control and protection features include negative logic ON/OFF control, power good, remote sense, user-adjustable overcurrent protection, low-power sleep mode, and full auto recovery protection.
The user-configurable sleep mode programs the power module into a low-power dissipation state during idle or light-load conditions.
The adjustable overcurrent protection reduces stress on both the power module and load and helps engineers reduce or eliminate external circuitry.
