Instructions for Use:
Power Input Connection:
- Connect the input power source to the VIN and GND pins. Ensure the input voltage is within the specified range.
Setting Output Voltage:
- The output voltage can be set using an external resistor divider network connected between VOUT, FB, and GND.
- Use the formula ( V_ = V_ times (1 + frac) ), where ( V_ = 0.9V ).
Component Placement:
- Place the inductor close to the SW pin for efficient switching performance.
- Ensure capacitors are placed near VIN and VOUT to minimize noise and improve stability.
Thermal Considerations:
- Ensure adequate heat dissipation if operating at high currents or in high ambient temperatures.
Protection Circuits:
- The device includes built-in over-current and thermal protection; no additional components are required for these functions.
Enabling/Disabling:
- To enable/disable the converter, use the EN pin. A high signal on EN enables the converter, while a low signal disables it.
Layout Recommendations:
- Follow good PCB layout practices, keeping traces short and wide, especially for high current paths, to reduce losses and improve efficiency.
