TPS7H4010-SEP: Power Dissipation

yehuda mermelstein

Part Number: TPS7H4010-SEP

Is there an equation that we can use to predict heat dissipation of the IC for different Vin , Vout, and I out? We require at least "New Space" electronics .

Hi Yehuda,

Extrapolating information from empirical data is the best way to predict power dissipation for your application. The PDF below shows plotted efficiency data we have taken on the TPS7H4010-SEP EVM for VOUT=1V at Fsw=500kHz. Are there any other specific Vin, Vout, and switching frequency configurations you would be interested in having data for?
