ISL8502IRZ-T - Renesas Electronics

Description: The ISL8502 is a synchronous buck controller with internal MOSFETs packaged in a small 4mm x 4mm QFN package. The ISL8502 can support a continuous load of 2A and has a very wide input voltage range. With the switching MOSFETs integrated into the IC, the complete regulator footprint can be very small and provide a much more efficient solution than a linear regulator. The ISL8502 is capable of stand alone operation or it can be used in a master slave combination for multiple outputs that are derived from the

ISL8502IRZ-T Frequently Asked Questions (FAQs)

  • A 2-layer or 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 input voltage rises and falls monotonically, and that the enable pin (EN) is properly driven to prevent unwanted start-up or shutdown. A soft-start circuit can also be used to reduce inrush current.
  • The maximum allowed capacitance is 220uF. Exceeding this value may cause instability or oscillations in the output voltage.
  • Implement overcurrent protection (OCP) and overtemperature protection (OTP) using external components or ICs. The ISL8502IRZ-T also has a built-in thermal shutdown feature that disables the device when the junction temperature exceeds 150°C.
  • Yes, the ISL8502IRZ-T is AEC-Q100 qualified and suitable for high-reliability and automotive applications. However, ensure that the device is used within its recommended operating conditions and that proper derating is applied.
