Flex Power Modules announces the PKM4516ADPIHS, the latest model in its series of DCDC converters aimed at radio frequency power amplifier (RFPA) applications in the telecom market.

The PKM4516ADPIHS is a high-density converter in the industry standard quarter-brick format, thus saving valuable board space. It has an output of 28V at 18A, output power up to 504W, and an input voltage range of 36V to 75V. This makes it ideal for 28V laterally diffused MOSFET (LDMOS) or gallium nitride (GaN) based RFPA applications.

The new converter has typical efficiency peaking at 95.5% at 48Vin and half load. It has a wide output voltage adjustment range of 14V to 35 V, allowing for easy optimization of the connected RF section.

Comprehensive protection is provided including short-circuit, overload, over-temperature, output over-voltage, and input under-voltage. Start-up into pre-biased loads is guaranteed, and the isolation rating is 2250Vdc from primary to secondary. A remote on/off control is provided with optional positive or negative logic.
