Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the TI application note 'TPS65283-1RGET PCB Layout Guidelines' (SLUAUH5) for optimal performance and thermal management.
The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. TI recommends using a low-ESR ceramic capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the output voltage. Refer to the datasheet and the TI application note 'TPS65283-1RGET Output Capacitor Selection' (SLUAUH6) for more information.
The TPS65283-1RGET has an absolute maximum input voltage rating of 18V, but the recommended maximum input voltage is 15V to ensure reliable operation and to prevent damage to the device.
The TPS65283-1RGET has a built-in overcurrent protection (OCP) feature that can be enabled by connecting the OCP pin to a resistor divider network. The OCP threshold can be set by selecting the appropriate resistor values. Refer to the datasheet and the TI application note 'TPS65283-1RGET Overcurrent Protection' (SLUAUH7) for more information.
The TPS65283-1RGET has a thermal derating of 1.5°C/W, which means that the device's power dissipation must be reduced by 1.5°C/W for every degree above the maximum operating temperature of 125°C to prevent overheating.
