Description:Switching Voltage Regulators 2.95-V to 18-V, stackable 20-A synchronous SWIFT buck converter with pin-strapping and PMBus 40-LQFN-CLIP -40 to 150
The maximum input voltage that can be applied to the TPS546B24ARVFR is 24V, as indicated in the datasheet. However, it's recommended to derate the input voltage to 22V to ensure reliable operation and to account for voltage spikes or transients.
To ensure the stability of the output voltage, it's essential to follow the recommended layout guidelines, use a sufficient output capacitor (at least 10uF), and ensure that the input voltage is within the recommended range. Additionally, the output voltage can be adjusted using the FB pin, and the output voltage tolerance can be improved by using a voltage reference IC.
The maximum output current that the TPS546B24ARVFR can deliver is 3A, as indicated in the datasheet. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations. It's essential to ensure that the device is operated within its recommended operating conditions to ensure reliable operation.
To handle thermal considerations for the TPS546B24ARVFR, it's essential to ensure that the device is operated within its recommended operating temperature range (-40°C to 125°C). The device should be mounted on a PCB with a sufficient thermal pad, and the ambient temperature should be kept below 85°C. Additionally, the device's thermal resistance (θJA) should be considered when designing the thermal management system.
To minimize EMI, it's essential to follow good PCB layout practices, such as separating the input and output stages, using a solid ground plane, and minimizing the loop area of the power traces. Additionally, the device's switching frequency (around 2.2MHz) should be considered when designing the EMI filter, and the device's EMI performance can be improved by using a shielded inductor and a common-mode choke.
