Texas Instruments recommends a compact layout with the TL3472CDRG4 placed close to the power supply pins, and the input and output capacitors placed as close as possible to the device. A star-ground configuration is also recommended to minimize noise and EMI.
To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output capacitor's ESR is less than 1 ohm. Additionally, use a low-ESR input capacitor and keep the input and output traces as short as possible. Avoid using long, thin traces and minimize the area of the power and ground planes.
The TL3472CDRG4 can handle input voltages up to 15V, but it's recommended to operate within the specified input voltage range of 2.7V to 12V for optimal performance and reliability.
The TL3472CDRG4 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 output voltage of the TL3472CDRG4 can be calculated using the formula: Vout = (1 + R1/R2) * Vref, where R1 and R2 are the feedback resistors, and Vref is the internal reference voltage (1.225V).
