Request LTM4650-1's thermal features

Dear All

Could you provide LTM4650-1's thermal features

1. LTM4650EY-1B#PBF

2. 

1) power dissipation:(LTM4650-1's power consumption)

2) thermal resistance(Junction-to-Case):

3) thermal resistance(Junction-to-Board):

4) Maximum operating junction temperature(or Case temperature):

Best regards

Lonnie Kim

  • Hello Lonnie,

    Datasheets has thermal parameters on page 2. See below. 125oC is the maximum temperature. 

    Power dissipation is mainly related to your input, output voltage, switching frequency and output current,

    also the ambient temperature.  You can check the efficiency curves from datasheet to estimate the loss or

    using the LTpowerCAD to estimate the loss.  

    Thanks
