L4960H datasheet by STMicroelectronics

L4960H Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L4960H can handle?
  The L4960H can handle a maximum input voltage of 40V, but it's recommended to keep it below 36V for reliable operation.
• How do I choose the right inductor value for my application?
  The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific application requirements.
• What is the purpose of the bootstrap capacitor (CBOOT) in the L4960H?
  The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage for the internal power MOSFET. It's essential for proper operation of the device.
• How do I ensure the L4960H is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor, and add a compensation network (R-C network) to the feedback pin if necessary.
• Can I use the L4960H in a synchronous rectification configuration?
  Yes, the L4960H can be used in a synchronous rectification configuration, which can improve efficiency. However, this requires additional external components and careful design consideration.
