ISL6562 is a two-phase buck PWM controller for microprocessor CORE voltage regulation. This device together with companion gate drivers, HIP6601A, HIP6602A, HIP6603A or HIP6604 and MOSFETs provides a precision voltage regulation system for advanced microprocessors to satisfy the ever increasing current demands of modern microprocessors.
The ISL6562 is a two‑phase current‑mode PWM controller designed for microprocessor core voltage regulation. It works with companion gate drivers and MOSFETs to provide precise voltage regulation, high ripple frequency, and fast transient response.
Key features include programmable VID codes (1.050 V‑1.825 V), built‑in PWRGD monitoring, over‑voltage and under‑voltage protection, and over‑current fold‑back. The datasheet provides pin‑out diagrams, absolute maximum ratings, electrical specifications, and package dimensions for SOIC and tape‑and‑reel options.
| Maximum Junction Temperature (Plastic Package) | 150 °C |
|---|---|
| Ambient Temperature Range | 0 °C to 70 °C |
| VID voltage range | 1.050 V to 1.825 V in 25 mV steps |
The VID pins accept voltages from 1.050 V to 1.825 V in 25 mV increments.
If the core voltage exceeds 24 % above the programmed level, the PWRGD output goes low to signal an over‑voltage condition.
The part is offered in a 16‑lead SOIC package (part number ISL6562CB) and in a tape‑and‑reel version (ISL6562CB‑T).
