Product Overview

The LT3470ITS8#TRMPBF is a compact, high-efficiency, low-noise step-down DC/DC converter from Linear Technology, designed for a wide range of applications. This miniature, integrated switch regulator packs a powerful punch, delivering continuous output currents up to 200mA with a high switching frequency of 1.2MHz. Its ability to convert input voltages from 4V to 40V down to a range of output voltages makes it versatile for various industrial, automotive, and portable power designs.

Key Features

• Wide Input Voltage Range: The device can handle input voltages from 4V to 40V, making it suitable for applications with varying power supplies.
• Adjustable Output Voltage: Users can set the output voltage from 1.25V up to 16V to suit their specific circuit requirements.
• High Efficiency: With its internal 0.5A switch, the LT3470ITS8#TRMPBF can achieve efficiencies up to 85%, ensuring minimal power loss during conversion.
• Low Quiescent Current: Its low quiescent current of 40µA (typical) during operation is ideal for battery-powered devices, extending their run time.
• Thermal Protection: The device features thermal shutdown and current limit protection, safeguarding it and the application from potential damage due to overheating or overcurrent conditions.
• High Switching Frequency: A 1.2MHz fixed frequency allows for small external components, reducing noise and minimizing the overall footprint of the power supply design.
• Stable with Low ESR Ceramic Capacitors: The converter operates stably with ceramic output capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) than other types.
