Toshiba recommends a 4-layer PCB with a solid ground plane and a separate power plane for the chip. The input and output tracks should be kept short and wide to minimize parasitic inductance and resistance. A detailed layout guide is available in the Toshiba application note.
To ensure stability, make sure to follow the recommended component values and PCB layout. Additionally, add a 10nF to 100nF capacitor between the VCC and GND pins to filter out noise. Also, ensure that the input and output capacitors are properly selected and placed close to the chip.
The maximum allowed voltage on the input pins is 5.5V, which is the absolute maximum rating. However, for normal operation, the recommended input voltage range is 2.7V to 5.5V. Exceeding the maximum rating can damage the chip.
The RN2106,LF is rated for operation up to 125°C. However, the chip's performance and reliability may degrade at high temperatures. It's recommended to derate the chip's performance and consider using a heat sink or thermal management system if operating in high-temperature environments.
To troubleshoot issues, start by checking the PCB layout and component values against the recommended values. Verify that the input and output capacitors are properly selected and placed. Use an oscilloscope to check the output voltage and current waveforms. If the issue persists, consult the Toshiba application note and contact Toshiba support for further assistance.
