The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help reduce input voltage ripple and improve overall system stability.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF to 100nF capacitor between the FB and VOUT pins to filter out noise and improve stability.
The maximum output current capability of the TPS3828-33DBVR is 3A. However, the actual output current capability may be limited by the input voltage, output voltage, and thermal considerations.
The TPS3828-33DBVR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's essential to consider thermal management and derate the output current accordingly.
The output voltage of the TPS3828-33DBVR can be adjusted by using a resistive divider network between the VOUT and FB pins. The output voltage can be calculated using the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
