Description
ISL6612ACBZ-T is a dual-channel, interleaved, multiphase buck regulator controller from Intersil (Renesas). It’s used to generate CPU/GPU core rails by driving two synchronized PWM outputs that switch external MOSFETs in a two-phase buck converter. Key features typically include: two outputs for interleaved phases, current-sense feedback, soft-start, enable, Power Good (PGOOD), and protection functions such as overcurrent/UVLO. It’s aimed at high-current DC‑DC applications like CPU/gPU VRMs, FPGA boards, and other low-voltage, high-current regulators. The “CBZ-T” suffix denotes the package type and tape-and-reel ordering. For exact electrical specs (input voltage range, switching frequency, pinout, and sense pins), refer to the official datasheet.
Features
ISL6612ACBZ-T features (concise):
- Dual PWM controllers for multiphase VRM applications (e.g., CPU core regulation)
- 2-phase interleaved operation with current-mode control
- Slope-compensated current limiting and phase sharing
- Programmable switching frequency (typical range suitable for VRMs)
- Error amplifier, feedback reference and adjustable output voltage with tracking
- Soft-start and programmable ramp; voltage droop/load-line control
- UVLO, enable/power-down and power-good signaling
- Overcurrent/short-circuit protection, overvoltage protection, and thermal shutdown
- Gate-drive outputs for external high-/low-side MOSFETs (external FETs required)
- Flexible control: synchronized or independent channels; suitable for multi-phase designs
Note: Exact frequency range and pin/package specifics are in the datasheet; this summarizes the common features for the ISL6612 family.
