NCP1050ST136T3 Frequently Asked Questions (FAQ)

  • The recommended PCB layout for optimal thermal performance involves placing the device on a 2-layer or 4-layer board with a solid ground plane on the bottom layer, and using thermal vias to connect the exposed pad to the ground plane. Additionally, keeping the copper traces wide and short can help to reduce thermal resistance.

  • To ensure reliable startup of the converter, make sure to follow the recommended startup sequence, which involves applying the input voltage before enabling the device. Also, ensure that the input voltage is within the specified range and that the output capacitor is properly sized to handle the inrush current.

  • The maximum allowed output capacitance for the NCP1050ST136T3 is 220uF. Exceeding this value can cause instability and affect the converter's performance.

  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.

  • The recommended input capacitor type is a low-ESR ceramic capacitor, such as an X5R or X7R dielectric. The recommended value is 10uF to 22uF, depending on the input voltage and current requirements.
