Digitally controlled point of load converter ideally suited for a wide range of applications

TDK Corporation has announced the introduction of the iJC series of 100A point of load non-isolated DC-DC converters with PMBus communication. These converters utilise adaptive digital control to deliver improved transient response and system stability across a wide range of output capacitance. Accepting an 8VDC to 14VDC input, the output voltage of the devices can be adjusted from 0.6V to 1.5V with currents of up to 100A and a maximum output power of 150W. With the current share function, converters can be paralleled to produce 180A, utilising either a PMBus command or an external resistor. Weighing just 20g and measuring 28mm x 35mm x 10mm, these ultra-compact converters are ideally suited for a wide range of applications, including communications, broadcast, industrial and test and measurement equipment. The read and write functionality of the PMBus allows precision, real-time monitoring of the output voltage, current and temperature. device’s operating parameters can also be easily programmed using the TDK-Lambda GUI interface. The converters can be used without the PMBus function through the use of function pins. The series will reliably operate across a wide -40C to +120C temperature range with minimal airflow, providing a true ‘useable’ power. High efficiency levels are maintained across light to full loads and are as high as 91.5% for a 1.5V output. Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
