ISL62392CIRTZ-T - Renesas Electronics

Description: The ISL62392C 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 ISL62392C 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

ISL62392CIRTZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in the application note AN1995, which includes guidelines for component placement, thermal management, and routing to minimize noise and ensure optimal performance.
  • The output voltage can be configured using the VID pins and an external resistor divider network. The datasheet provides a formula to calculate the required resistor values for a specific output voltage. Additionally, Renesas provides a VID code calculator tool to simplify the process.
  • The ISL62392CIRTZ-T can handle input voltages up to 28V, but it's recommended to operate within the specified input voltage range of 4.5V to 24V for optimal performance and reliability.
  • The ISL62392CIRTZ-T has built-in OCP and SCP features. The OCP threshold can be set using an external resistor, and the SCP response time can be adjusted using an external capacitor. The datasheet provides more information on how to implement these features.
  • The thermal derating curve is not explicitly provided in the datasheet, but it can be obtained from Renesas' technical support team or through a thermal simulation tool such as FloTHERM or ANSYS Icepak.
