A good PCB layout for the TPS26633RGER involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
When selecting input capacitors for the TPS26633RGER, consider the voltage rating, capacitance value, and ESR (Equivalent Series Resistance). A minimum capacitance of 10uF is recommended, with a voltage rating of at least 1.5 times the maximum input voltage. Low-ESR capacitors such as ceramic or film capacitors are preferred.
The TPS26633RGER can deliver up to 3A of output current, but this is dependent on the input voltage, output voltage, and thermal conditions. It's essential to check the thermal performance and power dissipation to ensure the device operates within its safe operating area.
The TPS26633RGER has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCSET pin and the GND pin. The value of the resistor determines the overcurrent threshold. A lower resistor value sets a lower overcurrent threshold, and vice versa.
The EN (Enable) pin is used to turn the device on or off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. The EN pin can be connected to a logic signal or a switch to control the power output.
