ISL95538BHRTZ

ISL95538BHRTZ is a Renesas Intersil power-management IC designed for multi‑output DC‑DC regulation. It generates multiple low‑voltage rails from a DC input, making it suitable for CPUs, memory, and other digital ICs in embedded, telecom, and industrial systems. The BHRTZ suffix denotes a RoHS‑compliant, lead‑free package variant.
Key features (typical): wide input range, multiple regulated outputs, programmable output voltages and switching frequency, current‑mode control, enable/shutdown control, programmable soft‑start, and protection features such as undervoltage, overcurrent/overvoltage, and thermal shutdown. It can be used with external MOSFETs or with integrated FETs, depending on configuration.
Applications include power management for computing, networking gear, embedded controllers, and industrial equipment.
For exact electrical specs, pinout, package details, and application notes, consult the official Renesas Intersil datasheet for ISL95538BHRTZ.

Pin count: 20 pins.
Function: ISL95538BHRTZ is a dual buck regulator controller (two-channel DC-DC converter) used to generate CPU/core rails. It drives external MOSFETs and provides features such as soft-start, current/overload protection, enable control, and power-good signaling.

Manufacturer: Renesas Electronics Corporation (Intersil brand; product is listed under Intersil/ISL95538).
What kind of company: Renesas is a Japanese multinational semiconductor company that designs and manufactures analog, power-management, and mixed-signal ICs (Intersil focuses on analog/power-management).

ISL95538BHRTZ is a multi-output DC-DC buck regulator controller used for high-efficiency rail generation. Common application areas include:
- Desktop/server motherboard VRMs (CPU/GPU/memory core and I/O rails)
- Multi-rail point-of-load regulators for FPGAs, ASICs, DSPs
- Notebook/embedded systems requiring compact, high-density power
- Telecom and data-center power modules
- Industrial equipment requiring compact, efficient multi-output DC-DC supplies
In short: high-performance, multi-rail VRM/mower power for CPUs, GPUs, memories, and other high-density loads.
