LX5591LQ-TR Frequently Asked Questions (FAQs)

  • Microchip provides a recommended PCB layout in the LX5591LQ-TR evaluation board user's guide, which includes guidelines for component placement, trace routing, and grounding to minimize EMI and noise.
  • To optimize power supply noise rejection, ensure that the input capacitors (CIN) are placed close to the device, and the output capacitors (COUT) are placed close to the load. Additionally, use a low-ESR capacitor for COUT and a high-quality, low-noise power supply.
  • The maximum output current capability of LX5591LQ-TR is 1.5A, but it's recommended to derate the output current based on the ambient temperature and the device's thermal performance to ensure reliable operation.
  • The LX5591LQ-TR has a built-in overcurrent protection feature that can be enabled by connecting the OCSET pin to a resistor divider network. The resistor values can be calculated based on the desired overcurrent threshold and the device's internal current sense amplifier gain.
  • To ensure reliable operation, it's recommended to provide adequate thermal management for LX5591LQ-TR, such as using a heat sink, thermal vias, and thermal pads. The device's thermal performance can be estimated using Microchip's thermal modeling tools and guidelines.
