Instructions for TPS51367RVER

1. Input Voltage Connection:

   • Connect the input voltage within the operating range (2.97V to 5.5V) to the VIN pin.

2. Output Voltage Setting:

   • Use external resistors R1 and R2 to set the output voltage according to the formula: [ V_ = 0.6V times left(1 + fracright) ]

3. Switching Frequency Configuration:

   • The switching frequency is fixed at 1.5MHz. No external components are required for frequency setting.

4. Efficiency Optimization:

   • Ensure the load current and input voltage are within the efficiency-optimized range to achieve up to 88% efficiency.

5. Quiescent Current Minimization:

   • Keep the quiescent current low by ensuring minimal load when not in use, maintaining it around 40μA.

6. Load and Line Regulation:

   • Maintain load regulation under 1mV and line regulation under 1mV/V to ensure stable output voltage across varying conditions.

7. Soft-Start:

   • Allow a soft-start time of approximately 4ms to prevent inrush currents during startup.

8. Enable Control:

   • Apply an enable voltage greater than 1.15V to activate the device.

9. Under-Voltage Lockout (UVLO):

   • Ensure the input voltage does not drop below the UVLO threshold of 2.97V to prevent operation under insufficient power supply.

10. Thermal Protection:

    • Monitor the thermal shutdown temperature of 160°C to protect against overheating.
