Instructions for Use:
- Circuit Design: Ensure that the input voltage is within the specified range of 2.5V to 28V. The output voltage can be adjusted from 0.8V up to the input voltage level.
- Component Placement: Place the inductor and output capacitor close to the MP2467DN-LF-ZZ to minimize noise and improve transient response.
- Thermal Considerations: Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures.
- Power-Up Sequence: No specific power-up sequence is required, but ensure all components are properly powered before operation.
- Layout Recommendations: Follow good PCB layout practices to reduce EMI and improve performance. Keep traces short and wide for ground and power connections.
- Capacitor Selection: Choose low ESR capacitors for both input and output to ensure stable operation and efficient performance.
- Inductor Selection: Select an inductor based on the desired output current and ripple requirements. Refer to the datasheet for recommended values.
- Enable/Shutdown Pin: To place the device into shutdown mode, pull the enable pin low. The shutdown current will be less than 1μA.
- Feedback Network: Set the output voltage using an external resistor divider connected to the feedback pin. Refer to the datasheet for detailed calculations.
