TPS26620-23EVM: Thermal distribution

Part Number: TPS26620-23EVM
Other Parts Discussed in Thread: TPS2662


My customer is considering to use the TPS2662x and concerning thermal characteristics.

For their reference, could you provide thermal distribution at full load condition on the EVM?

Best Regards,


  • Hi Kuramochi,

    We will get back in a couple of days.

  • Hello Kuramochi-San,

    With TPS2662 or similar device, thermal dissipation plays a major role during start-up of device. Once the output has reached input voltage (VIN = VOUT), the dissipation in device is significantly reduced. At full load current (0.88A), the dissipation in TPS2662 device will be ~0.4W [=I2R] after the start-up.

    During start-up, power dissipation can be controlled by setting tdVtT with a cap on dVdT pin. This is described in Section of the datasheet.

    Let us know if you have any further queries.
