What are the key features of LT8711EUDC#PBF?
- Wide 4.5 V to 42 V input range covering automotive, industrial, and telecom bus voltages
- Current-mode PWM control for fast transient response and inherent cycle-by-cycle current limiting
- Multi-topology support (buck, boost, inverting) from a single controller IC reducing BOM count
- Micropower quiescent current enabling high efficiency in light-load and battery-powered applications
- Compact 20-pin QFN (PQCC-N20) footprint with exposed pad for enhanced thermal dissipation
What is LT8711EUDC#PBF used for?
The LT8711EUDC#PBF is designed for automotive 12 V and 24 V bus step-down/step-up regulators, industrial point-of-load converters, and telecom equipment where a single controller must support multiple topologies with up to 42 V input capability. Its micropower quiescent current keeps standby power low in always-on vehicle modules such as telematics units and door control nodes. The current-mode PWM architecture provides excellent line and load regulation, making it ideal for powering FPGAs, DSPs, and mixed-signal payloads in space-constrained embedded systems.

Frequently Asked Questions
What input voltage range does the LT8711EUDC#PBF support, and which power bus architectures does it cover?
The LT8711EUDC#PBF accepts input voltages from 4.5 V to 42 V, covering standard 5 V USB, 12 V automotive, 24 V industrial, and 36 V telecom bus architectures in a single controller that eliminates the need for topology-specific ICs.
How does current-mode PWM control in the LT8711EUDC#PBF improve transient response compared to voltage-mode controllers?
Current-mode control in the LT8711EUDC#PBF samples the inductor current every switching cycle, allowing the controller to respond to load transients within 1 to 2 switching cycles and inherently limiting peak switch current without external current-sense comparators, improving reliability in 12 V automotive buck regulators.
Which multi-topology conversion modes does the LT8711EUDC#PBF support, and how does that reduce design cost?
The LT8711EUDC#PBF supports buck, boost, and inverting DC/DC topologies from a single 20-pin QFN controller, allowing engineers to use one part number across multiple products and reducing qualification, inventory, and BOM cost compared to maintaining 3 separate topology-specific regulators.
What thermal management does the 20-pin QFN package of the LT8711EUDC#PBF provide for high-power switching designs?
The 20-pin QFN package (PQCC-N20) includes an exposed thermal pad on the bottom that conducts heat directly to the PCB copper plane, achieving junction-to-board thermal resistance below 30°C/W in typical 4-layer PCB layouts, enabling full-power operation in compact automotive ECU modules.
