Texas Instruments recommends a compact layout with the input and output capacitors placed close to the device. The device should be placed near the power source, and the output voltage should be routed away from the input. A 4-layer PCB with a solid ground plane is recommended. Refer to the TI application note 'TPS60140PWP Layout and Placement Guidelines' for more details.
To ensure stability, follow the recommended component values and layout guidelines. Use a minimum of 10uF input capacitance and 10uF output capacitance with low ESR. The output capacitor should be placed close to the device. Avoid using ceramic capacitors with high ESL, as they can cause oscillation. Additionally, ensure the device is properly decoupled from the power source.
The TPS60140PWP can handle a maximum input voltage of 5.5V. However, it's recommended to operate the device within the specified input voltage range of 2.7V to 5.5V to ensure reliable operation and minimize the risk of damage.
The TPS60140PWP is rated for operation up to 85°C. However, the device's performance and reliability may degrade at higher temperatures. If your application requires operation above 85°C, consider using a different device or implementing thermal management techniques to keep the device within its specified operating temperature range.
The output voltage of the TPS60140PWP is determined by the resistor divider network consisting of R1 and R2. The output voltage can be calculated using the formula: Vout = 1.2V x (1 + R2/R1). Ensure that the resistors are chosen to provide the desired output voltage within the specified range of 1.2V to 5.5V.
