What are the key features of LT3472EDD#PBF?
- Dual-output topology providing positive output 1.25 V to 34 V and negative output down to -34 V from a single 2.2 V to 16 V input rail
- Current-mode PWM switching regulator with fast transient response suitable for automotive-grade and industrial power supply designs
- Compact 10-pin DFN package with exposed thermal pad enables high power density layouts in space-constrained automotive systems
What is LT3472EDD#PBF used for?
The LT3472EDD#PBF is designed for automotive systems such as ADAS modules, infotainment, and instrumentation that require both positive and negative supply rails from a single battery input. It is also used in industrial analog front-end circuits, op-amp bias supplies, and TFT LCD bias networks that need split rails up to ±34V. Its wide 2.2V to 16V input range allows compatibility with 3.3V, 5V, and 12V power buses.

Frequently Asked Questions
What output voltage range does the LT3472EDD#PBF support on its positive and negative outputs?
The LT3472EDD#PBF generates a positive output adjustable from 1.25 V to 34 V and a negative output adjustable down to -34 V, both derived from a single input voltage between 2.2 V and 16 V. This dual-rail capability makes it highly suitable for analog circuits, op-amp bias supplies, and TFT LCD drivers that require split supply rails.
For automotive designs, why is the LT3472EDD#PBF a good choice for dual-rail power supplies?
The LT3472EDD#PBF operates from a 2.2 V to 16 V input, covering the automotive 12 V battery rail, and generates both positive and negative outputs up to ±34 V in a single 10-pin DFN package. Its current-mode PWM control provides stable regulation under load transients typical in automotive ADAS, infotainment, and cluster display systems.
How does the 10-pin DFN package with exposed pad benefit thermal management in the LT3472EDD#PBF?
The 10-pin DFN package with an exposed thermal pad allows direct heat transfer to the PCB copper layer, significantly reducing junction-to-ambient thermal resistance. This enables the LT3472EDD#PBF to deliver higher continuous output power across its 2.2 V to 16 V input range without requiring external heat sinks in compact automotive or industrial board designs.
