Overview
The LT8619EDD#PBF is a compact, high-efficiency, high-speed synchronous monolithic step-down switching regulator manufactured by Analog Devices Inc. It features an input voltage range up to 60V and delivers a typical output current of 1.2A. The device consumes only 6μA of quiescent current, ensuring minimal power loss in standby modes. It operates within a temperature range of -40°C to 125°C and utilizes a 10-pin WDFN package with an exposed pad for thermal management.
Feature Summary
- Synchronous monolithic buck regulator architecture
- Ultra-low 6μA quiescent current consumption
- High efficiency operation across wide load ranges
- Integrated soft-start functionality
Applications
- Industrial control systems
- Distributed power architectures
- Battery-powered equipment
- Point-of-load regulation
Procurement Notes
Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the DFN package type matches your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.
Selection Notes
Select this component for applications requiring high input voltages up to 60V with moderate output currents. The low quiescent current makes it suitable for battery-operated devices where standby power is critical. Consider the thermal performance of the exposed pad design for heat dissipation needs in compact enclosures.
Part Context
This part belongs to the LT8619 family of synchronous buck regulators from Analog Devices. It is designed for space-constrained applications needing high efficiency and fast transient response. The family includes variants with different packages and pinouts, but all share the core high-voltage, low-quiescent-current architecture.
Replacement Considerations
LT8619IDD#PBF offers similar electrical characteristics in a different package configuration. LT8619IMSE-5#PBF provides equivalent performance in an MSOP package. Verify pinout compatibility and thermal requirements when substituting these variants.
