Instructions:
- Power Connection: Connect the input voltage (VIN) to a power supply within the specified range of 4.5V to 17V.
- Output Configuration: Set the desired output voltage using an external resistor divider network connected to the FB pin.
- Switching Frequency Setting: The switching frequency is fixed at 600kHz; no external components are required for this setting.
- Current Limit Adjustment: Ensure that the load does not exceed the maximum output current limit to prevent damage to the device.
- Thermal Management: Monitor the operating temperature to avoid exceeding the thermal shutdown threshold of 160°C.
- Enable/Disable Control: Use the EN pin to control the enable or disable state of the device. When disabled, the device will enter a low-power shutdown mode consuming approximately 0.1μA.
- Capacitor Selection: Choose appropriate input and output capacitors to ensure stable operation and meet ripple requirements.
For detailed design considerations and application circuits, refer to the datasheet provided by the manufacturer.
