Description:The ISL62882 is a multiphase PWM buck regulator for microprocessor or graphics processor core power supply. The multiphase buck converter uses interleaved phases to reduce the total output voltage ripple with each phase carrying a portion of the total load current, providing better system performance, superior thermal management, lower component cost, reduced power dissipation, and smaller implementation area. The ISL62882 uses two integrated gate drivers to provide a complete solution. The PWM modulator is

ISL62882HRTZ-T Frequently Asked Questions (FAQs)
Renesas provides a recommended PCB layout guide in the ISL62882HRTZ-T evaluation board user manual, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The ISL62882HRTZ-T has a resistive divider network that sets the output voltage. By changing the values of the resistors, you can configure the device for different output voltages. Renesas provides a voltage calculation formula in the datasheet to help with this process.
While the datasheet specifies a maximum input voltage of 25V, it's recommended to derate the input voltage to 22V to ensure reliable operation and prevent damage to the device.
The ISL62882HRTZ-T has built-in OCP and SCP features. To implement these features, you need to connect the OCP and SCP pins to the input voltage and output voltage rails, respectively, and set the threshold values using external resistors. Renesas provides more information on how to do this in the datasheet and application notes.
Renesas provides a thermal derating curve in the datasheet, which shows the maximum power dissipation of the device as a function of ambient temperature. This curve helps you determine the maximum output current and power dissipation of the device at different temperatures.
