Instructions for Using TPS65988CERJTR

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply source.
   • Ensure the input voltage is within the specified range of 2.7V to 5.5V.

2. Output Configuration:

   • Set the output voltages (VOUT1 and VOUT2) using external resistors or through the I2C interface if supported.
   • VOUT1 and VOUT2 can be adjusted between 1.8V and 3.3V.

3. Load Connection:

   • Connect the load to the respective output pins (VOUT1 and VOUT2).
   • Ensure the load current does not exceed the maximum continuous output current of 1000mA.

4. Efficiency Considerations:

   • The typical efficiency is around 90% for both VOUT1 and VOUT2 when operating at 3.3V input and 1A output current.
   • Optimize the design for high efficiency by minimizing parasitic losses and selecting appropriate components.

5. Thermal Management:

   • Ensure proper thermal management to keep the junction temperature below 125掳C.
   • Use a heatsink or thermal pad if necessary, especially under high load conditions.

6. Shutdown Mode:

   • To reduce power consumption, use the shutdown feature by pulling the shutdown pin low.
   • The shutdown current is typically 0.1渭A at VIN = 5V.

7. Operating and Storage Temperature:

   • Operate the device within the temperature range of -40掳C to 85掳C.
   • Store the device within the temperature range of -65掳C to 150掳C.

8. ESD Protection:

   • Handle the device with care to avoid damage from electrostatic discharge.
   • The device has an ESD rating of 4000V according to the Human Body Model.

9. Package Handling:

   • The device is available in a 24-pin QFN package with dimensions of 4x4mm.
   • Follow standard PCB assembly guidelines for surface mount devices.

10. Testing and Validation:

    • Perform initial testing and validation to ensure the device meets the required specifications.
    • Monitor the performance under various operating conditions to ensure reliability.
