Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as keeping the input and output traces short and away from each other, using a solid ground plane, and minimizing parasitic inductance and capacitance.
To ensure stability, follow the recommended compensation network values and layout, and ensure that the output capacitor is properly sized and placed. Additionally, avoid using long input traces, and use a low-ESR output capacitor. If oscillations occur, try adding a small series resistor (e.g., 10 ohms) between the output and the feedback pin.
The LM6134BIN has an absolute maximum input voltage rating of 15V, but the recommended maximum input voltage is 12V to ensure reliable operation and prevent damage to the device.
The LM6134BIN is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. Ensure that the device is properly heatsinked and that the maximum junction temperature is not exceeded. Consult the datasheet for thermal derating information.
The output voltage ripple can be estimated using the equation: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency. Consult the datasheet for more information on output voltage ripple and how to minimize it.
