PKJ4000 series
700W Half Brick Isolated DC/DC Converter for RFPA applications
The PKJ4000 series is a powerful isolated DC/DC converter in a half brick format. There are 2 variants: one with an output range of 14-35V at up to 25A and the other 25-55V at up to 14A, offering an output power of 700W. This makes it ideal for both LDMOS and GaN based RFPA applications.
This converter has a high efficiency up to 96.5% typical at 48Vin, 28Vout and 100% load.
The PKJ series can operate over a temperature range from -40°C up to +85°C and offers an MTBF of up to 6.7 million hours.
Standard features for this model include comprehensive protection such as short-circuit, overload, over-temperature, output over-voltage, input under-voltage. A remote on/off control is provided, and isolation is 1500V.
