The maximum operating temperature range for the AUIPS2031R is -40°C to 150°C, with a junction temperature of up to 175°C.
To ensure proper biasing, the AUIPS2031R requires a minimum of 5V on the VCC pin and a minimum of 2.5V on the VIN pin. Additionally, the input voltage (VIN) should be at least 1V higher than the output voltage (VOUT).
For optimal performance, it is recommended to follow a 4-layer PCB design with a solid ground plane, and to keep the input and output capacitors as close to the device as possible. Additionally, the PCB should be designed to minimize parasitic inductance and resistance.
The output voltage ripple can be calculated using the following 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.
The recommended input capacitor is a 10uF ceramic capacitor with an X7R or X5R dielectric, and the recommended output capacitor is a 22uF ceramic capacitor with an X7R or X5R dielectric.
