Description

LT3472EDD is an LED driver IC from Linear Technology (Analog Devices). It’s a high-efficiency switching regulator that provides constant-current drive to LEDs from a wide input voltage, using buck-boost topology. The “EDD” suffix identifies the package variant (8-pin MSOP-like package).
Key points:
- Wide input range (suitable for automotive and variable supplies)
- Buck-boost LED driver with programmable current via a sense resistor
- External inductor and diode; PWM and/or analog dimming options
- Protection features (short-circuit, thermal, current limit)
- Can drive one or more LED strings configured for constant current
Typical uses include automotive lighting, display/backlight, and general LED lighting where input voltage can vary widely. For exact specs (LED current range, efficiency, switching frequency, and pinout), consult the LT3472 datasheet for the EDD package.

Features

LT3472EDD features (concise):
- Dual, independent buck controllers with current-mode control
- Wide input voltage range (up to ~60V)
- External feedback per channel for adjustable outputs
- Fixed-frequency PWM with soft-start
- Overcurrent/short-circuit protection (hiccup)
- Overvoltage protection and thermal shutdown
- Enable/shutdown control
- High efficiency operation for compact power designs
- Suitable for two-channel, compact power supplies in the EDD package
Note: Always verify exact specs (voltages, currents, package details) from the latest LT3472 datasheet for your specific variant.

Package

LT3472EDD is offered in a 16‑lead TSSOP package.

Pinout

- Pin count: 16 pins (TSSOP-16 with exposed pad, as indicated by the EDD suffix)
- Function: Dual high‑voltage constant‑current LED driver with two independent current sinks; uses external sense resistors to set LED current; includes control/feedback pins for regulation and enable.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
Company type: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits (ADI acquired Linear Technology, the original owner of the LT3472, in 2017).

Application

LT3472EDD is a dual-channel, constant-current LED driver (buck-boost capability). Typical applications:
- Automotive lighting (headlamps, taillights, interior)
- LCD backlighting and signage
- Architectural and display lighting
- Portable/battery-powered LED lighting
- Multi-string LED installations needing independent current regulation and dimming (PWM or analog) over wide input voltages.
