The new iJC series of 100A Point of Load (POL) non-isolated DC/DC converters has been announced by TDK Corporation 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 8-14VDC input, the output voltage of the iJC can be adjusted from 0.6-1.5V 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 28.0x35.0x10.0mm, these ultra-compact converters are 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. The iJC’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 iJC series will reliably operate 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.
Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
