ISL5857IAZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use short, wide traces for the power lines and keep the sensitive analog signals away from the digital signals.
  • To ensure stability, ensure that the output capacitor is within the recommended range (10uF to 100uF), and the ESR is within the recommended range (0.1Ω to 10Ω). Also, make sure the input capacitor is within the recommended range (1uF to 10uF) and the input voltage is within the recommended range (2.7V to 5.5V).
  • The maximum ambient temperature range for the ISL5857IAZ is -40°C to +85°C. However, the device can operate up to +125°C with derating.
  • The power dissipation of the ISL5857IAZ can be calculated using the formula: Pd = (Vin x Iin) + (Vout x Iout). Where Vin is the input voltage, Iin is the input current, Vout is the output voltage, and Iout is the output current.
  • A low-ESR ceramic capacitor (X5R or X7R) with a value between 1uF to 10uF is recommended for the input capacitor.
