Présentation
Description
LT8609SIV#WPBF is a production variant of Analog Devices’ LT8609S wide‑input, synchronous buck‑boost regulator in the WPBF Pb‑free package. The SIV suffix denotes the device revision/lot code, and WPBF identifies the packaging (tape & reel). The LT8609S is a versatile converter that can regulate an output across a broad input range by operating in buck, boost, or buck‑boost mode, with integrated high‑ and low‑side MOSFETs. It uses current‑mode PWM, supports adjustable switching frequency, and includes protections such as undervoltage lockout, overcurrent, and thermal shutdown. An external resistor divider sets the output, and enable/diagnostic pins enable system control. Typical applications include automotive and industrial power supplies, battery-powered systems, and any design requiring a stable output from a wide input range. For exact specs (input range, output current, efficiency, pinout), consult the LT8609S datasheet and WPBF packaging details.
Pinout
- Pin count: 8 pins (8-pin WPBF package).
- Function: High-voltage synchronous buck-boost DC-DC regulator with integrated MOSFETs; wide input range and adjustable output via feedback for stepping voltage up or down to a regulated Vout.

Application
LT8609SIV#WPBF is a wide-input, multi-output DC-DC regulator family. Common application areas include:
- Automotive power systems (12–24V, harsh environments)
- Industrial automation and robotics (multi-rail supplies)
- Telecom and networking equipment (mult rails and point-of-load)
- CPU/ASIC VRMs and other embedded power rails
- Battery charging and power-path management
- Solar energy harvesting and microgrid/battery-fed systems
- Portable/compact devices requiring efficient, multi-rail regulation
It’s well-suited for any design needing multiple regulated rails from a wide input with high efficiency.
