개요

Description

LT8609SIV#WPBF is an Analog Devices (Linear Tech) wide-input buck-boost regulator IC. The SIV suffix denotes the automotive/industrial-grade revision; #WPBF refers to the specific WPBF package.
Key points:
- Wide input, buck-boost power converter: can regulate an output below or above the input.
- Integrated power stage: two N-channel MOSFETs and control circuitry for high efficiency.
- Flexible operation: adjustable output via external resistors, with current‑mode control and protections.
- Protections: undervoltage/overvoltage, overcurrent, thermal shutdown, and soft-start.
- Intended use: automotive and battery-powered applications, DC-DC rails from 4.5–60V (typical range varies by revision).
For exact electrical specs, pinout, package details, and application circuits, consult the LT8609SIV data sheet and product page on Analog Devices’ website.

Package

QFN (leadless) package with an exposed pad (WQFN style); WPBF denotes Pb-free variant.

Pinout

- Pin count: 28 pins
- Function: A wide-input synchronous buck-boost switching regulator (converter), with (typically) integrated MOSFETs for efficient step-up/step-down regulation.

Manufacturer

Manufacturer: Analog Devices, Inc. (the Linear Technology brand after acquisition).
Company type: A global/multinational semiconductor company that designs, manufactures, and markets analog, mixed-signal, and DSP integrated circuits.

Application

- Automotive (12–24V) power supplies
- Industrial and motor-drive systems
- Solar/battery charging and energy harvesting
- Telecom/datacom power rails
- Portable/battery-powered devices
- LED lighting drivers
- General point-of-load regulation in consumer/industrial electronics
