Ericsson Introduces Full-Brick DC-DC Converter As Drop-In Replacement For New & Old 24V Input Designs

Ericsson Power Modules announced its dc-dc converter platform for RF power amplifier applications, which utilizes the industry standard full-brick format and footprint, making it a suitable drop-in replacement that is said to offer enhanced performance. The device, aimed at the telecoms market and customers developing base transceiver stations in cellular radio networks where high efficiency and reliability are required, is also suitable for many other applications, such as cooling fan trays.

The PKY2616PI delivers 600W output power and is said to typically exceed 94% efficiency. The device’s efficiency curve is virtually flat from 30 to 100% load. This level of performance is achieved by using a specially optimized topology and advanced rectification techniques (patent pending).

The device is designed for 24Vdc system voltages and has an input voltage range of 18-36V. For safety and availability, it can withstand up to 50V input continuously. The output voltage is factory set at 28V and the device features an ultra-wide output voltage trimming range that can be adjusted from 32 down to 10V, which is said to make the PKY2616PI extremely flexible and useful for different RF power amplifier technologies and applications, as well as other applications that require a regulated voltage, such as cooling fan trays in forced convection cooled equipment.

The PKY2616PI has a typical 20mV load and line regulation with ±1% set voltage over a base-plate temperature range of -40 to 100°C. The device delivers full power at 100°C base plate temperature, and uses only high-reliability ceramic capacitors. Fully current-limit protected, the device has overvoltage protection on input and output connections. The PKY4716PI fully complies with ROHS requirements.

In OEM quantities the PKY2616PI is priced at $77.
