Instructions for Use:
Input Connection:
- Connect the input voltage (VIN) to the positive terminal and ground (GND) to the negative terminal.
- Ensure the input voltage is within the specified range (4.5V to 28V).
Output Configuration:
- Adjust the output voltage (VOUT) using the external resistor divider network if required.
- The output voltage can be set between 1.0V and 5.5V.
Load Connection:
- Connect the load to the output terminals (VOUT and GND).
- The maximum continuous output current is 2.0A.
Thermal Management:
- Ensure adequate heat dissipation to prevent the device from exceeding the maximum operating temperature (125°C).
- Use a heatsink if necessary, especially under high load conditions.
Protection Features:
- The device includes short-circuit protection (SCP) and over-temperature protection (OTP).
- In case of a short circuit, the device will auto-restart with a cycle time of 1ms.
- The device will shut down if the temperature exceeds 160°C.
Start-Up and Shutdown:
- The start-up time is approximately 2ms when the input voltage rises from 0 to 5V.
- Ensure a smooth and controlled power-up sequence to avoid transient issues.
Storage and Handling:
- Store the device in a dry environment within the storage temperature range (-55°C to 150°C).
- Handle the device with care to avoid damage to the pins and components.
