100A PMBus digitally-controlled PoL converter

June 19, 2017 // By Graham Prophet
TDK’s iJC series of 100A point of load (POL) non-isolated DC-DC converters are equipped with PMBus communication; the converters employ adaptive digital control to deliver improved transient response and system stability across a wide range of output capacitance.

Use of PMBus allows precise, real-time monitoring of the output voltage, current and temperature. The iJC’s operating parameters can also be programmed using the TDK-Lambda GUI interface. The converters can be used without the PMBus function through the use of function pins.


The iJC series is rated to operate across a -40 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.
