The recommended layout and placement for the TPS3806I33DBVT can be found in the Texas Instruments application note 'TPS3806 Layout and Placement Guidelines' (SLVAE04). It provides guidance on component placement, routing, and thermal considerations to ensure optimal performance and reliability.
The output voltage of the TPS3806I33DBVT can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.182V), R1 is the resistance between the VOUT and FB pins, and R2 is the resistance between the FB pin and GND. The datasheet provides a detailed example of how to calculate the output voltage.
The maximum input voltage that the TPS3806I33DBVT can handle is 6.5V. Exceeding this voltage may cause damage to the device or affect its performance. It's recommended to ensure that the input voltage is within the specified range to ensure reliable operation.
The TPS3806I33DBVT has a built-in overvoltage protection (OVP) feature that can be enabled by connecting a resistor (R_OVP) between the OVP pin and GND. The OVP threshold voltage is 1.182V x (1 + R_OVP/100kΩ). When the input voltage exceeds the OVP threshold, the device will shut down to protect the load.
The EN (enable) pin on the TPS3806I33DBVT is used to enable or disable the device. When the EN pin is pulled high (above 1.4V), the device is enabled, and when it's pulled low (below 0.4V), the device is disabled. This pin can be used to implement power sequencing or to turn off the device when not in use.
