LP87524BRNFTQ1 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.
  • Ensure that the input voltage rises monotonically during start-up and falls monotonically during shutdown. A soft-start capacitor can be added to slow down the start-up time if necessary.
  • The maximum output current capability of the LP87524BRNFTQ1 is 3A per channel. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations.
  • The output voltage can be configured using the FB pin and an external resistor divider network. The resistor values can be calculated using the formula provided in the datasheet.
  • The EN pin is an active-high enable input that allows the device to be turned on or off. Connect the EN pin to a logic high to enable the device, and connect it to a logic low to disable the device.
