ISL6228HRTZ-T - Renesas Electronics

Description: The ISL6228 IC is a dual channel synchronous-buck PWM controller featuring Intersil's Robust Ripple Regulator (R3) technology that delivers truly superior dynamic response to input voltage and output load transients. Integrated MOSFET drivers and bootstrap diodes result in fewer components and smaller implementation area. Intersil's R3 technology combines the best features of fixed-frequency and hysteretic PWMs while eliminating many of their shortcomings. R3 technology employs an innovative modulator that

ISL6228HRTZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the application note AN1443, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The selection of input and output capacitors depends on the specific application requirements. Renesas recommends using low-ESR capacitors with a minimum capacitance of 10uF for the input and output. The application note AN1443 provides more detailed guidance on capacitor selection.
  • The ISL6228HRTZ-T is rated for operation from -40°C to +125°C ambient temperature range, making it suitable for high-reliability applications.
  • The ISL6228HRTZ-T has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor and capacitor network. The application note AN1443 provides a detailed example of how to implement overcurrent protection.
  • The recommended input voltage range for the ISL6228HRTZ-T is 4.5V to 14V, although the device can operate from 4V to 15V. Operating outside the recommended range may affect performance and reliability.
