54V±5%

6.48 A±5%

Note:

1.The voltage value shall be the test value at the connector;

2.If the input voltage is low, the current value needs to be raised to meet TDP 350W specification;

4.2.2 Peak current of power supply

MLU290-M5 Intelligent Accelerating Card is able to reduce power consumption adjustment for

transient power changes above the µs level. the power regulator can support power fluctuations within

the ms level (e.g .1.2 x TDP).

4.2.3 HSC protection circuit

MLU290-M5 Intelligent Accelerating Card input voltage is DC 54V.Hot Swap Controllers (HSC) is

required on the baseboard to provide slow start, short circuit protection and over-current/voltage

protection for MLU290-M5. It is recommended to provide a separate HSC for each MLU290-M5. The

transient power consumption need to support more than 2 ms within 1.6 *TDP.The block diagram of

HSC is as follows:
