Toshiba recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a separate power plane for the input and output. The input and output capacitors should be placed as close as possible to the IC, and the feedback resistors should be placed close to the output pin.
To ensure stability, it's essential to follow the recommended PCB layout, use a sufficient output capacitor (at least 10uF), and ensure that the feedback resistors are properly sized. Additionally, the input voltage should be well-regulated, and the output should not be overloaded.
The maximum ambient temperature for the RN1706,LF is 85°C, but it's recommended to derate the output current and voltage according to the temperature derating curve provided in the datasheet.
While the RN1706,LF is a high-quality device, it's not specifically designed for high-reliability or automotive applications. Toshiba recommends using their automotive-grade or high-reliability products, such as the TB9043FNG or TB9045FNG, for these types of applications.
The output voltage ripple can be calculated using the formula: 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.
