ISL8500IRZ - Renesas Electronics

Description: The ISL8500 is a high-performance, simple output controller that provides a single, high frequency power solution for a variety of point-of-load applications. The ISL8500 integrates a 2A standard buck PWM controller and switching MOSFET. The PWM controller in the ISL8500 drives an internal switching N-Channel power MOSFET and requires an external Schottky diode to generate an output voltage from 0.6V to 19V. The integrated power switch is optimized for excellent thermal performance up to 2A of output curren

ISL8500IRZ Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the ISL8500IRZ evaluation board user manual, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • The ISL8500IRZ requires a bias voltage on the EN pin to enable the device. A 10kΩ pull-up resistor to VIN and a 100nF capacitor to GND are recommended to ensure proper biasing and noise filtering. Additionally, the input voltage should be within the recommended range of 4.5V to 18V.
  • The ISL8500IRZ is capable of delivering up to 0.5A of output current, but this can be limited by the thermal performance of the PCB and the input voltage. It's essential to ensure the device is properly cooled and the input voltage is within the recommended range to achieve the maximum output current.
  • The ISL8500IRZ has built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) features. However, additional protection can be achieved by using external components such as TVS diodes or voltage regulators to protect against voltage transients and spikes.
  • Renesas recommends using a 10μF to 22μF ceramic capacitor with an X7R or X5R dielectric as the input capacitor. This helps to filter out noise and ensure stable operation.
