LTC3780EUH#PBF

DC DC Switching Controllers Overview

The LTC3780EUH#PBF is a high-efficiency, synchronous four-switch buck-boost switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 36 V and supports output voltages from 800 mV to 30 V. The device delivers up to 10 A of output current through a single output channel. Key electrical parameters include a typical static current of 1.5 mA and a switch frequency capability up to 400 kHz. It features a load regulation of -0.1% and operates within a temperature range of -40°C to +85°C. The component is housed in a 32-lead QFN package.

DC DC Switching Controllers Feature Summary

• Synchronous four-switch topology enables efficient operation in buck, boost, and buck-boost modes regardless of input-to-output voltage relationships.
• Integrated control architecture eliminates the need for external microcontrollers or complex logic for standard power conversion applications.
• Supports programmable switching frequency to optimize performance for specific design requirements.

DC DC Switching Controllers Applications

• Automotive DC/DC converters requiring wide input voltage ranges
• Industrial power supply systems needing flexible step-up/step-down capabilities
• Battery-powered equipment where input voltage varies significantly above or below the required output level

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards before procurement. Confirm that the EUH package variant matches your PCB footprint requirements. Check current availability status as distribution channels may report limited stock or restricted supply conditions for this specific part number.

DC DC Switching Controllers Selection Notes

Select this controller when a single IC must handle both step-up and step-down operations without transformer isolation. Ensure the external MOSFET selection supports the 10 A current capability and thermal requirements. Verify that the desired switching frequency falls within the 400 kHz operational limit for optimal efficiency.
