What are the key features of LT3579EUFD#PBF?
- 6 A switch current rating enables high-power boost conversion from a 2.5 V to 16 V input with minimal external components
- Current-mode PWM control provides inherent cycle-by-cycle current limiting and fast load-transient response for dynamic loads
- Integrated fault protection features including short-circuit and over-temperature shutdown safeguard the power supply and downstream circuitry
What is LT3579EUFD#PBF used for?
The LT3579EUFD#PBF is used in boost regulators that convert 5 V to 12 V or higher for industrial sensor supplies, and in inverting converters that generate negative rails for op-amp bias in data acquisition systems. Its 2.5 V to 16 V input range makes it suitable for single-cell lithium-ion to 12 V bus applications in portable instrumentation and telecom line cards. The integrated fault protection simplifies compliance with IEC 62368-1 safety requirements in consumer and industrial power supply designs.

Frequently Asked Questions
What is the input voltage range and peak switch current of the LT3579EUFD#PBF?
The LT3579EUFD#PBF operates from a 2.5 V minimum to 16 V maximum input voltage and supports up to 6 A peak switch current, enabling boost conversion from single-cell Li-ion or 5 V bus to output voltages exceeding 12 V in compact power supply designs.
How does current-mode PWM control benefit the LT3579EUFD#PBF in applications with rapidly changing loads?
Current-mode PWM control in the LT3579EUFD#PBF senses inductor current on a cycle-by-cycle basis, allowing the regulator to respond to load transients within 1 to 2 switching cycles and naturally limiting peak inductor current to prevent saturation at switching frequencies up to 2.4 MHz.
What package does LT3579EUFD#PBF use and how does it affect thermal management?
The LT3579EUFD#PBF is housed in a 20-lead QFN (R-PQCC-N20) package with an exposed pad that conducts heat to the PCB copper pour, achieving a junction-to-board thermal resistance low enough to support full 6 A switch operation with a proper ground plane and at least 400 mm² of copper area.
When should a designer choose LT3579EUFD#PBF over a simpler boost converter for a 5 V to 12 V rail in industrial equipment?
LT3579EUFD#PBF is the better choice when the application requires both boost and inverting conversion from a single IC, needs integrated fault protection for IEC 62368-1 compliance, or demands 6 A switch current to supply loads above 1 A from a 2.5 V to 5 V input without an additional current-limit circuit.
