概述

Description

The LT3469ETS8#TRPBF is a low power, high efficiency, step-up (boost) DC/DC converter designed by Analog Devices (formerly Linear Technology). It is packaged in an 8-lead Thin Shrink Small Outline Package (TSSOP) and is suitable for applications requiring a compact design, like portable devices.
This converter can efficiently convert low input voltages (as low as 1.2V) to higher voltages (up to 34V), making it ideal for powering LEDs, battery-operated devices, and other applications requiring a stable voltage boost. The device features a high switching frequency, which allows the use of small external components, reducing overall board space. It also includes features like an internal soft-start, over-voltage protection, and adjustable output voltage, enhancing its versatility.
The LT3469 is appreciated for its reliability and performance, making it a popular choice in designs needing efficient power management.
