Instructions for Use:

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply ensuring it is within the range of 2.9V to 5.5V.

2. Battery Charging:

   • Connect the battery to be charged to the VBAT pin. Ensure the battery charge current does not exceed the maximum rating of 3.0A.

3. Output Configuration:

   • Set the desired output voltage (VOUT) using the feedback resistors. Verify that the maximum output current does not exceed 2.0A.

4. Enable Pin (EN):

   • To enable the device, set the EN pin high. For shutdown, pull the EN pin low to reduce power consumption.

5. Thermal Management:

   • Monitor the device temperature to ensure it does not exceed 160°C to prevent thermal shutdown.

6. Quiescent and Shutdown Currents:

   • When no load is connected, the quiescent current will be approximately 75μA. In shutdown mode, the current draw will be about 0.1μA.

7. Efficiency Monitoring:

   • Check the efficiency at typical operating conditions (VIN = 4.2V, VOUT = 3.3V, IOUT = 1A) to ensure optimal performance around 90%.

Note: Always refer to the datasheet provided by Linear Technology/Analog Devices for detailed specifications and application notes.
