ISL6327IRZ-T - Renesas Electronics

Description: The ISL6327 controls microprocessor core voltage regulation by driving up to 6 synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area. Microprocessor loads can generate load transients with extremely fast edge rates. The ISL6327 utilizes Intersil's p

ISL6327IRZ-T Frequently Asked Questions (FAQs)

  • The recommended PCB layout for optimal performance involves keeping the high-current paths short and wide, using a solid ground plane, and placing the input and output capacitors close to the IC. A 4-layer board with a dedicated power plane and a solid ground plane is recommended. Refer to the application note AN1143 for more details.
  • The selection of input and output capacitors depends on the specific application requirements. For the ISL6327IRZ-T, a low-ESR ceramic capacitor with a minimum capacitance of 10uF is recommended for the input capacitor. For the output capacitor, a low-ESR ceramic capacitor with a minimum capacitance of 22uF is recommended. The capacitor selection should also consider the voltage rating, ripple current, and temperature range.
  • The maximum operating temperature range for the ISL6327IRZ-T is -40°C to +105°C. However, the device can operate up to +125°C with derating. Refer to the datasheet for more information on thermal derating.
  • The ISL6327IRZ-T has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The resistor values can be calculated based on the desired overcurrent threshold. Refer to the datasheet for more information on overcurrent protection implementation.
  • The recommended voltage range for the enable pin is 2.5V to 5.5V. The enable pin should be driven high to enable the device and low to disable it. A voltage above 2.5V is required to ensure proper operation.
