Description

Features

ISL41387IRZ features (concise):
- High-performance synchronous buck regulator controller in an 8-pin IRZ package
- Wide input voltage operating range
- Adjustable switching frequency
- Current-mode PWM control for tight regulation and fast transient response
- Soft-start and programmable output rise
- Enable/Shutdown control input
- Protection: undervoltage lockout, overvoltage protection, cycle-by-cycle current limit
- Overcurrent/short-circuit protection and thermal shutdown
- Power-good/status or fault indication
- Low quiescent current and compact footprint
Note: exact electrical specs (ranges, voltages, frequencies) are in the datasheet.

Pinout

- Pin count: 16 pins (IRZ package).
- Function: Dual/multi-phase synchronous buck regulator controller for DC-DC conversion (CPU core-type VRM), providing PWM control signals to high-side/low-side FETs, with features like adjustable frequency and power-good signals.

Manufacturer

ISL41387IRZ is manufactured by Renesas Electronics Corporation (formerly Intersil; the Intersil brand is now part of Renesas). Renesas is a Japanese multinational semiconductor company that designs and manufactures analog, power-management, and mixed-signal integrated circuits.
