Instructions for Use

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply within the specified range (2.7V to 5.5V).
   • Ensure proper decoupling capacitors are placed close to the input and output pins to maintain stability.

2. Output Configuration:

   • Set the desired output voltage using external resistors connected to the feedback (FB) pin.
   • Refer to the datasheet for the specific resistor values required to achieve the desired output voltage.

3. Enable/Shutdown Control:

   • The enable (EN) pin can be used to turn the device on or off. Apply a high signal to enable the device and a low signal to shut it down.
   • In shutdown mode, the device consumes minimal current (ISD).

4. Thermal Management:

   • Ensure adequate heat dissipation by providing a good thermal path from the package to the PCB.
   • Avoid operating the device beyond its maximum junction temperature (TJ).

5. Layout Considerations:

   • Place the input and output capacitors as close as possible to the respective pins to minimize parasitic inductance.
   • Use wide traces for power and ground connections to reduce resistance and improve thermal performance.

6. Protection Features:

   • The device includes overcurrent protection (OCP), overvoltage protection (OVP), and thermal shutdown (TSD) to prevent damage under fault conditions.
   • Ensure that the load does not exceed the maximum load current (ILOAD) to avoid triggering protection features.

7. Storage and Handling:

   • Store the device in a dry environment within the specified storage temperature range.
   • Handle with care to avoid static discharge, which can damage the device.
