Visão Geral
Description
ISL6625ACRZ-T is a dual-channel, multiphase PWM controller from Renesas/Intersil used to build DC-DC buck regulators for core voltage rails (CPU/GPU, memory, telecom).
What it does:
- Generates two synchronized PWM outputs to drive external MOSFETs in a multiphase buck converter.
- Supports phase matching for multi‑phase operation to improve transient response and efficiency.
- Offers programmable switching frequency and either voltage- or current-mode control, plus soft-start.
Key safety/features:
- Enable and soft-start control, Power-Good/monitoring, overcurrent protection, undervoltage lockout, and thermal/overload protection.
- Feedback via resistor network to set output voltage, with a configurable ramp.
Packaging:
- ACRZ-T indicates RoHS-compliant packaging (lead-free) in a specific small PCB package (e.g., TSSOP/VSSOP family).
Typical uses:
- VRMs for CPUs/GPUs, memory power regulators, and other high-current DC-DC applications requiring reliable, multi-phase regulation.
Note:
- Check the datasheet for exact electrical specs (input range, fSW, Vout range) and recommended external components.
