Note 1: The specs on ripple noise and efficiency are for the input voltage of 5V and rated load.
Note 2: Ripple noise is measured over 20MHz bandwidth, with MLCCs of 47uF at input and 22uF at output.
Note 3: Depending on ambient temperature, cooling airflow may be required.


Ultra-fast Response

Support for the latest LSI requirements such as FPGAs and ASICs

When choosing a power supply, it tends to select a power supply based on current required, however, there is a knack to make large LSIs work stably. While it is common practice to place a capacitor required by LSI nearby, it is also important to study power supply well.

Although place a large value of capacitor to suppress the voltage dips in power line is a common way, the problem can be solved by using power supply with ultra-fast response.

MGT Power Supply

Our ultra-fast response BSV series were selected as the power supply for Xilinx FPGA’s MGT daughter card among products from other makers.

Those have long been used as the power supplies for new ICs evaluation in Xilinx and Altera laboratories in California.

1) Hi-precision, Hi-stability (Allowable Voltage Range: +/-30mV)
2) Noise (10mVp-p or less)

With BSV series from Bellnix, required noise value for MGT power supplies can be satisfied.
