DC DC Switching Controllers datasheet and documents for ISL6559CB-T
DC DC Switching Controllers Overview
The ISL6559CB-T is a current mode PWM controller designed for core-voltage regulation. It drives two to four interleaved synchronous-rectified buck-converter channels in parallel. The device supports output voltage adjustment from 0.8V to 1.55V and delivers up to 120A of current. Operating frequencies range from 80kHz to 1000kHz. It is housed in a 32-pin QFN package with an exposed pad.
DC DC Switching Controllers Feature Summary
- Provides core-voltage regulation by driving multiple interleaved synchronous-rectified buck-converter channels in parallel
- Utilizes current mode PWM control architecture for precise power management
- Supports flexible switching frequency configuration across a wide operational range
DC DC Switching Controllers Applications
- Processor core voltage regulation
- Multi-phase synchronous buck converter designs
- High-current DC-DC power supply systems
DC DC Switching Controllers Procurement Notes
Verify the specific suffix 'CB-T' against official Renesas or Intersil documentation to confirm pinout, thermal characteristics, and tape-and-reel specifications. Ensure compatibility with the target PCB footprint and thermal relief requirements for the 32-pin QFN EP package before procurement.
DC DC Switching Controllers Selection Notes
Select this component when designing multi-phase power stages requiring high current capability up to 120A. Consider the adjustable frequency range for EMI optimization and the voltage range for compatibility with low-voltage digital cores. Evaluate thermal performance needs given the QFN package type.
DC DC Switching Controllers Part Context
This part belongs to the Intersil (now Renesas) ISL6559 family of multi-phase PWM controllers. These devices are engineered for high-efficiency power delivery in computing and communication applications where stable core voltages are critical for processor operation.
DC DC Switching Controllers Replacement Considerations
Consult official datasheets for direct pin-to-pin replacements within the ISL6559 series or newer Renesas equivalents. Verify that any substitute maintains the same interleaved channel count support and current handling capabilities.
