ISL98602IRAAZ - Renesas Electronics

Description: The ISL98602 represents a high-power, integrated LCD supply IC targeted at large panel LCD displays. The ISL98602 integrates a high-power boost converter for AVDD generation, VON and VOFF charge pump drivers, one synchronous buck regulator, and one synchronous buck controller for two logic voltages. The VON slicing circuitry and power good function are also included. Operating at 1. 3MHz, the AVDD boost converter features a 5. 5A boost FET. Feedback is taken from the far side of the delay FET for improving

ISL98602IRAAZ 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 device is properly decoupled, and the input voltage is within the recommended range. Also, follow the recommended PCB layout and thermal management guidelines.
  • The maximum allowed capacitance for the output capacitor is 220uF. Exceeding this value may cause instability or oscillations.
  • While it's possible to use a different inductor value, it's not recommended. The recommended inductor value is optimized for the device's operating frequency and output voltage. Using a different value may affect the device's performance and stability.
  • Check the soft-start capacitor value and ensure it's within the recommended range. Also, verify that the input voltage is within the recommended range and the device is properly decoupled.
