[In Stock] Supply Original LT3471EDD (ADI) Dual-Channel Boost Converter, DFN-10
LT3471EDD — 1.3A, 1.2MHz Boost/Negative Output Converter Details:
I. Product Overview
The LT3471EDD dual-channel switching regulator integrates two 42V, 1.3A switches with an error amplifier capable of ground-level sensing, providing both boost and negative output conversion functionality. Operating at a 1.2MHz switching frequency, the LT3471EDD permits the use of compact, low-cost, low-profile inductors and capacitors. With a 42V switching rating, it is an ideal choice for boost converters up to ±40V, as well as SEPIC and flyback designs.

III. Product Features
The LT3471EDD offers the following key characteristics:
High Integration and Flexible Configuration: The chip integrates two independent 1.3A, 42V switches. It can be configured as two boost converters, one boost converter and one negative output converter, or two negative output converters, providing exceptional design flexibility.
High-Performance Output: Supports output voltages up to ±40V and delivers high output current. For instance, it can deliver 5V/630mA output from a 3.3V input, 12V/320mA output from a 5V input, or -12V/200mA output.
High-Frequency Switching and Compact Packaging: A fixed high-frequency switching frequency of 1.2MHz permits the use of smaller, lower-cost inductors and capacitors, contributing to a reduced overall solution footprint. The chip itself utilises a compact 3mm x 3mm DFN package with a height of just 0.75mm, making it highly suitable for space-constrained applications.
Low Power Consumption and Reliability: Features a low VCESAT switch (330mV @ 1.3A), contributing to improved efficiency. Extremely low shutdown current (< 1µA) helps conserve power consumption. The programmable soft-start function, configurable via an external RC network to set the current ramp rate, effectively eliminates high inrush currents during startup.
Wide Input Voltage Range: The broad input range of 2.4V to 16V makes it suitable for diverse power sources, including lithium-ion batteries, multi-cell alkaline/NiMH batteries, and 12V mains supplies.
IV. Application Areas
The characteristics of the LT3471EDD make it highly suitable for the following applications:
Display and Lighting Drivers: Ideal for powering organic light-emitting diode (OLED) and white light LED drivers. Also suitable for TFT-LCD bias power supplies.
Portable Electronics: Commonly used in digital cameras, cellular telephones (mobile phones), and similar devices to generate required voltage rails.
Communication Equipment: Employed in the power sections of devices such as xDSL modems.
Industrial and Medical Equipment: Suitable for medical diagnostic devices and industrial control modules requiring local ±5V or ±12V power supplies.
