ISL95538BHRTZ-T

ISL95538BHRTZ-T is a power-management IC from Intersil/Renesas in the ISL9553x family. It’s used for DC-DC voltage conversion to generate core rails in digital systems.
What it is: a synchronous buck regulator/controller that provides a regulated output from a higher input, suitable for CPU/GPU core voltages and other rails in computers, servers, or telecom gear.
Key features (typical, as per datasheet concepts): wide input range, programmable output voltage via external resistors, adjustable switching frequency, current-mode control, overcurrent/short‑circuit protection, thermal shutdown, enable and fault/diagnostic outputs. Packaging is RoHS-compliant; the -TZ suffix indicates a tape-and-reel/pouch delivery variant.
Typical use: design a DC-DC power stage (single or multi-rail) with good efficiency, fast transient response, and protection features.
Note: for exact electrical specs, pinout, and application circuits, consult the official datasheet. Want me to summarize its datasheet or provide a typical schematic?

Pin count: 28 pins (QFN package, BHRTZ-T variant).
Function: Multi-output synchronous buck regulator/controller IC used for DC-DC VRMs; provides PWM/gate-drive control to external FETs for multiple voltage rails (e.g., CPU core and other rails).

- Manufacturer: Renesas Electronics Corporation (the Intersil brand).
- What kind of company: A global semiconductor company that designs and manufactures analog and power-management integrated circuits; originally Intersil (U.S.), acquired by Renesas in 2017 and now part of Renesas Electronics.
