Description
ISL80020AFRZ-T is a high‑efficiency DC‑DC switching regulator IC from Intersil/Renesas (ISL). It integrates the control logic and switching FETs to convert a higher input voltage to a lower, stable output in a compact package, suitable for MCU cores, memory rails, and other system rails. The AFRZ‑T suffix indicates a surface‑mount package with tape‑and‑reel packaging.
Key features:
- Wide input range and adjustable output via feedback
- High efficiency and low quiescent current
- Protections: enable, undervoltage, overcurrent, thermal shutdown
Usage:
- Follow the datasheet reference design: add inductor, input/output capacitors, feedback resistors, and set EN/soft-start as needed.
For exact electrical specs, pinout, and app circuit, I can summarize from the datasheet if you’d like.
