Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good thermal design practices, such as using a solid ground plane, placing thermal vias under the device, and keeping the thermal path short and direct.
To ensure accurate voltage sensing, it's crucial to follow the recommended pin connections, use a low-impedance voltage source, and minimize noise and interference on the voltage sense lines. Additionally, consider using a voltage sense resistor with a low temperature coefficient to minimize errors.
The maximum allowed voltage on the VSENSE pin is 6.5V, which is higher than the recommended operating voltage of 5.5V. However, it's essential to ensure that the voltage on the VSENSE pin does not exceed 6.5V to prevent damage to the device.
The TPS3600D33PWRG4 is rated for operation up to 125°C, but it's essential to consider the device's power dissipation and thermal management when operating in high-temperature environments. Ensure that the device is properly heatsinked and that the thermal design is adequate to prevent overheating.
The power dissipation of the TPS3600D33PWRG4 can be calculated using the formula: Pd = (VIN - VOUT) x IOUT x Efficiency. The efficiency of the device can be found in the datasheet, and the input and output voltages and currents should be measured or calculated based on the application.
