100A digitally controlled PoL converter is PMBus compliant

June 16, 2017 // By Julien Happich
TDK's iJC series of 100A Point of Load (POL) non-isolated DC-DC converters are designed with PMBus communication.

The converters use adaptive digital control to deliver improved transient response and system stability across a wide range of output capacitance. Accepting an 8 to 14Vdc input, the output voltage of the iJC can be adjusted from 0.6 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. The read and write functionality of the PMBus allows precision, real-time monitoring of the output voltage, current and temperature. Operating parameters can also be programmed using the TDK-Lambda GUI interface. Alternatively, the converters can be used without the PMBus function through the use of function pins. The iJC series reliably operates across a wide -40 to +120ºC 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. The 28.0x35.0x10.0mm units weigh just 20g. Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
