Stockholm, SwedenEricsson Power Modules' latest DC/DC converter platform, the PKY4716PI, uses the industry-standard full-brick format and footprint, making it a suitable drop-in replacement for applications in the telecom and industrial sectors.
According to Ericsson, the PKY4716PI delivers 700W output power and typically exceeds 94 percent efficiency. the PKY4716PI's efficiency curve is virtually flat from 30 percent to 100 percent load. Ericsson attributes this performance level to a specially optimized topology and advanced rectification techniques.
The device will handle both 48V and 60V system voltages and has an input voltage range of 36-75V. For safety and availability, it can withstand up to 100V input continuously. The device features an ultra-wide output voltage trimming range that can be adjusted down to 10V, making the PKY4716PI extremely flexible and useful for different RF power amplifier technologies and applications, as well as other applications with varying supply voltage requirements.
The PKY4716PI has a typical 20mV load and line regulation with ±1 percent set voltage over a base-plate temperature range of -40 to 100 degrees C. The device delivers full power at 100 degrees C base plate temperature, and uses only high-reliability ceramic capacitors. Fully current-limit-protected, the device has over-voltage protection on input and output connections. The PKY4716PI fully meets ROHS requirements and, with its low component count, offers high reliability.
Pricing: $85 each in OEM quantities.
