While the datasheet specifies an operating junction temperature range of -40°C to 125°C, it's essential to consider the module's thermal derating. Above 85°C, the module's output power derates, and the continuous output current capability reduces. Ensure your design considers this thermal limitation to maintain reliability and performance.
The TPSM843620SITR's output voltage accuracy is ensured by the internal voltage reference and the feedback loop. However, to maintain accuracy, keep the output voltage sense lines as short as possible and away from noise sources. Additionally, use a suitable output capacitor to filter out any noise or ripple.
The recommended input capacitor type and value depend on the input voltage, power rating, and ESR requirements. In general, a low-ESR, X5R or X7R ceramic capacitor with a value between 10 μF to 22 μF is suitable for most applications. Consult the datasheet and application notes for specific guidance.
To achieve high efficiency, ensure the input voltage is as close to the output voltage as possible, minimize the input and output capacitance, and use low-ESR capacitors. Additionally, optimize the PCB layout to reduce parasitic inductance and resistance. Refer to the datasheet and application notes for efficiency optimization guidelines.
Yes, you can parallel multiple TPSM843620SITR modules to achieve higher output current. However, it's crucial to ensure that each module's output voltage sense lines are connected to a common voltage sense point, and the modules are properly synchronized to avoid oscillations.
