ISL62392CIRTZ - Renesas Electronics

Description: The ISL62392C controller generates supply voltage for battery-powered systems. It includes two pulse-width modulation (PWM) controllers, adjustable from 0. 6V to 5. 5V, and a linear regulator (LDO3) that generates a fixed 3. 3V and can deliver up to 100mA. The ISL62392C includes on-board power-up sequencing, a power-good (PGOOD) output, digital soft-start, and internal soft-stop output discharge that prevents negative voltages on shutdown. The patented R3 PWM control scheme provides a low jitter system with

ISL62392CIRTZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power paths.
  • Ensure that the output capacitor is properly sized and placed close to the IC. Also, make sure the input voltage is within the recommended range, and the input capacitor is properly sized and placed close to the IC.
  • The maximum ambient temperature for reliable operation is 85°C, but it's recommended to keep it below 70°C for optimal performance and reliability.
  • While the datasheet recommends a specific inductor value and type, you can use a different one as long as it meets the required inductance and current rating. However, this may affect the device's performance and efficiency.
  • Start by checking the input voltage, output voltage, and current. Verify that the device is properly soldered and the PCB layout is correct. Use an oscilloscope to check for oscillations or noise on the output.
