15 V/50 mA PFM Step−Up DC−DC Converter

Instructions for NCP1403SNT1G:

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply, ensuring it is within the range of 2.7V to 5.5V.
   • Ensure the output voltage (VOUT) is connected to the load requiring a stable 3.3V.

2. Capacitor Requirements:

   • Place a ceramic capacitor (typically 1μF) close to the input pin for stability and noise reduction.
   • Use a similar capacitor on the output side to maintain regulation and transient response.

3. Thermal Considerations:

   • The device should be placed on a PCB with adequate copper area to dissipate heat, especially under high current conditions.
   • Ensure that the operating temperature does not exceed 85°C.

4. PCB Layout:

   • Keep the traces short and wide to minimize inductance and resistance.
   • Ensure proper grounding and shielding to avoid interference.

5. Handling Precautions:

   • This component is sensitive to electrostatic discharge (ESD); handle with appropriate ESD precautions.
   • Avoid exposing the device to environments beyond its specified operating conditions.

6. Testing:

   • Before deploying in a final application, test the regulator under various load conditions to ensure it meets performance requirements.
   • Verify the dropout voltage and quiescent current to confirm efficiency and stability.
