Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI and noise.
Choose input capacitors with low ESR (Equivalent Series Resistance) and high ripple current rating to minimize voltage drops and ensure stable operation. Output capacitors should have low ESR and high capacitance to filter output voltage ripple. Consult the datasheet for specific recommendations and consider using X5R or X7R ceramic capacitors.
The TPSM63603SRDHR is rated for operation up to 85°C ambient temperature, but it's essential to consider the device's thermal characteristics, such as junction temperature (TJ) and thermal resistance (RθJA), to ensure reliable operation in your specific application.
The TPSM63603SRDHR has built-in OCP and SCP features. To implement these features, connect the OCP pin to a resistor divider network that sets the current limit, and connect the SCP pin to a capacitor that sets the short-circuit detection time. Consult the datasheet for specific implementation details and recommended component values.
The TPSM63603SRDHR is designed to operate with input voltages between 2.7V and 5.5V. Operating within this range ensures optimal performance, efficiency, and reliability. However, the device can tolerate input voltages up to 6V for short periods, but this may affect performance and reliability.
