概述

Description

LT8648SHV#WPBF is Analog Devices’ high‑voltage variant of the LT8648, a compact wide-input DC‑DC buck‑boost regulator in an 8‑pin WPBF package. The SHV suffix denotes the high‑voltage grade version, and WPBF is the Pb‑free package code (tape/ reel). This device can regulate output over a wide input range by automatically switching between buck and boost modes, making it suitable for automotive and industrial applications where input voltage swings above or below the desired output.
Key points:
- Wide input range with buck‑boost operation
- Synchronous switching with current‑mode control
- Overcurrent/thermal protection and soft‑start
- Small, Pb‑free WPBF package
For exact electrical specs, pinout, and application details, consult the LT8648 datasheet and product page for the WPBF variant.

Features

Here are the typical features of the LT8648SHV#WPBF (datasheet-level overview):
- Wide input range up to 60 V, suitable for automotive/industrial applications.
- Buck-boost regulator with seamless transition between buck and boost modes.
- Synchronous operation with internal high-side/low-side MOSFETs for high efficiency.
- Programmable output voltage via external feedback network; adjustable switching frequency.
- Protection features: overvoltage, undervoltage, overcurrent (cycle-by-cycle limit), short-circuit protection, and thermal shutdown.
- Soft-start and fault protection with enable/power-on reset options.
- Good transient response and high efficiency across load conditions.
- Compact WPBF packaging with good thermal performance and exposed pad.
Notes: For exact electrical specs (input range, output current, efficiency curves, exact pinout, and programming details), please refer to the LT8648SHV datasheet and the WPBF package guide.
