SLVSGS9E March 2023 – June 2024 TPS61299
PRODUCTION DATA
The maximum junction temperature is restricted to 125°C under normal operating conditions. Calculate the maximum allowable dissipation, PD(max), and maintain the actual power dissipation less than or equal to PD(max). The maximum-power-dissipation limit is determined using Equation 5.

The TPS61299x/xA comes in a WCSP or SOT583 package. The real junction-to-ambient thermal resistance of the package greatly depends on the PCB type and layout. Using thick PCB copper and soldering GND pin to a large ground plate enhances the thermal performance. Using more vias connects the ground plate on the top layer and bottom layer around the IC without solder mask also improves the thermal capability.
