Description

LT3467EDDB is the evaluation/development board for the LT3467 LED driver IC from Linear Technology (now Analog Devices). The LT3467 is a high-efficiency constant-current LED driver that can operate in buck, boost, or buck-boost mode to drive one or more LEDs from a wide input range.
Key points:
- EDDB = Evaluation/Development Board: a ready-to-use circuit that demonstrates a typical LT3467 application.
- Demonstrates adjustable LED current via the sense resistor and control inputs (including dimming/brightness control).
- Includes the essential external components: inductor, switching diode, current-sense resistor, LED string, input/output connectors, and test points for characterization.
- Useful for fast prototyping, performance testing, and validating LED strings and geometries before designing a final production board.
For exact specifications, operating ranges, and wiring, consult the LT3467 datasheet and the LT3467EDDB user guide.

Features

Here are the typical features of LT3467EDDB:
- Three constant-current LED driver channels
- Internal boost regulator to power LED strings from a low input
- Individual channel current programmable via sense resistors
- Dimming: PWM input and analog/dimming control options
- Fault protection: overcurrent/short-circuit, undervoltage lockout, thermal shutdown
- EN/UVLO control and soft-start to prevent inrush
- High efficiency over a wide input voltage range
- Compact EDDB package (space-efficient, suitable for backlight/applications)
Note: exact electrical figures (current range, input range, efficiency) are in the datasheet.

Package

The LT3467EDDB is supplied in an 8‑lead, 3 mm × 3 mm DFN surface‑mount package with an exposed thermal pad (RoHS/lead‑free).

Pinout

The LT3467EDDB is a 10-pin package (3 mm × 3 mm DFN with exposed thermal pad). Pin functions (summary):
- VIN: input supply
- GND: ground (exposed pad tied to ground)
- SW1, SW2: internal switching nodes for the two boost converters (connect to inductors)
- LED1, LED2: regulated current outputs / LED string connections (switching/feedback nodes to the LEDs)
- RUN1, RUN2: enable/shutdown pins for each LED channel
- ISET1, ISET2: current-set pins (program LED current with external resistors)
In short: a dual boost LED driver in a 10-pin DFN — VIN/GND, two switch nodes, two LED outputs, two RUN/EN pins and two ISET pins.

Manufacturer

Manufacturer: Linear Technology Corporation (LT), now part of Analog Devices, Inc.
What kind of company: Linear Technology was an American semiconductor company specializing in high-performance analog integrated circuits—power management, LED drivers, amplifiers, data converters, and related analog ICs. After ADI's 2017 acquisition, LT parts are produced and supported under the Analog Devices umbrella.

Application

Applications of LT3467EDDB:
- White LED backlighting for LCDs and displays
- Portable/battery-powered LED lighting and flash illumination
- Automotive LED lighting (interior/exterior) and signaling
- Signage and backlit displays
- Dimmable, high-efficiency constant-current LED driver for wide input ranges and boost/buck-boost configurations
