ISL62392HRTZ-T - Renesas Electronics

Description: The ISL62392 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 ISL62392 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 f

ISL62392HRTZ-T 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. Avoid routing sensitive analog signals near the switching node.
  • Ensure good airflow around the IC, and use a thermal pad or heat sink if necessary. Monitor the junction temperature (TJ) and adjust the operating conditions or thermal design as needed to keep TJ below 125°C.
  • Not using the EN pin can lead to unexpected behavior or damage to the IC. To use it correctly, connect EN to a logic-level input signal (e.g., from a microcontroller) to enable or disable the converter. Ensure the EN pin is properly terminated and decoupled.
  • Choose capacitors with low ESR, high ripple current rating, and a voltage rating that exceeds the maximum input or output voltage. X5R or X7R ceramic capacitors are suitable for most applications. Consult the datasheet for specific recommendations.
  • Use a common-mode choke and differential-mode capacitors to filter EMI. Shield the converter and surrounding components with a metal enclosure or shielded cable. Ensure good grounding and decoupling to minimize radiation.
