DC-DC converters are electronic systems that convert single voltage supply into higher or lower voltage. RP90Q-4815SRW/N-HC is a high- power DC-DC converter which also offers hot-swap support by providing an ultracapacitor-backed power rail. It is designed to provide regulated and isolated power from a nominal input voltage of 48V. It provides an output of regulated 15V and 900W with 94% efficiency in a wide range of operating temperature.

RP90Q-4815SRW/N-HC is applicable in variety of Industrial applications ranging from telecommunication systems, cloud computing systems, base station, battery charger, distributed power systems, point of load applications, solar power systems, electric vehicles etc. It has proved to be exceptionally reliable in difficult environments. The built-in N+1 redundancy with hot-swap support also make it suitable for applications where high reliability, high power and no single-point-of-failure is required.

The working principle of RP90Q-4815SRW/N-HC is based upon a galvanically-isolated DC boost converter as main stage. This involves a full-bridge selenium rectifier, an active front-end active clamp technology, and a main MOSFET switch. The two-stage topology consists of a rectification bridge and an isolated PFC stage. A forward-type synchronous buck is then used to convert the nonregulating PFC output voltage to a regulated 15V output voltage. The on-board control loop implements the current-mode control technique for fast load transient response and phase-shift modulation technique for compensation of input ratio variations resulting from different input line voltage. The built-in N+1 redundancy with hot-swap support makes it suitable for applications where high reliability and no single-point-of-failure are required.

RP90Q-4815SRW/N-HC is a very efficient DC-DC converter with high power capability. It has been proven to be an excellent choice for extreme conditions with its high reliability and rugged design. It has emerged as one of the most reliable and efficient DC-DC converters, and can be used for variety of industrial applications.
