概述

Description

ISL85009FRZ-T is Renesas Intersil’s high‑efficiency, multi‑rail DC‑DC switching regulator (power management IC). It combines multiple synchronous buck/boost regulators in a single FRZ‑T package to generate several rails from one input, saving board space and improving efficiency and sequencing control.
Key features (typical): wide input range; multiple adjustable outputs; integrated MOSFETs; programmable output voltages and rail sequencing; soft‑start; fault/STATUS reporting; and protections for overcurrent, overvoltage, and overtemperature with thermal monitoring.
Control/interface: designed for flexible control via dedicated pins and standard digital interfaces per family (see datasheet for exact options).
Typical applications: multi‑rail power for CPUs/GPUs, memory, telecom/network equipment, automotive, and other embedded systems requiring compact, efficient power management.
Note: refer to the latest datasheet for exact electrical specs, pinout, and programming options.

Features

I don’t have the exact datasheet memorized. ISL85009FRZ-T is a low-voltage buck regulator from Intersil/Renesas. Typical features you can expect (check the datasheet for exact values):
- Synchronous buck regulator with integrated high-side switch
- Wide input voltage range (low-voltage rail)
- Fixed or adjustable output options
- Fixed switching frequency with PWM/current-mode control
- High efficiency across load ranges
- Enable/Power-Down control
- Soft-start and controlled output ramp
- Overcurrent/short-circuit protection
- Overtemperature protection
- Undervoltage lockout
- Power‑good/diagnostic status
- Small package; FRZ-T denotes tape-and-reel option
For exact specifications (input range, max output current, voltage accuracy, etc.), please refer to the official datasheet.

Package

Package: 8-lead DFN, 2.0 mm × 2.0 mm (RZ). The “-T” suffix indicates tape-and-reel shipping.
