Overview
The LT8350RV#PBF is a synchronous Buck-Boost switching regulator from Analog Devices, housed in a 32-LQFN package. It supports an input voltage range of 3 V to 40 V and delivers up to 5 A output current with adjustable output voltages between 1 V and 18 V. The device operates at a fixed 2 MHz switching frequency and features a low quiescent current of 2 uA. It functions within a temperature range of -40°C to +150°C and includes shutdown capability.
Feature Summary
- Silent Switcher architecture minimizes electromagnetic interference radiation without requiring external filters.
- Integrated synchronous rectification provides high efficiency across buck and boost operating modes.
- Wide input voltage range accommodates single-cell lithium-ion batteries and higher bus voltages.
Applications
- Automotive systems requiring robust power regulation under varying battery conditions
- Industrial equipment needing isolated or non-isolated DC-DC conversion
- Telecommunications infrastructure power supplies
Procurement Notes
Verify the specific suffix 'RV' against the official datasheet to confirm pinout and thermal pad configuration. Ensure the order quantity matches the manufacturer's standard tray packaging requirements. Confirm RoHS compliance status for your region before finalizing procurement.
Selection Notes
Select this component when a wide input voltage range and high current density are required in a compact footprint. The 2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider thermal performance carefully due to the high current capability in a small LQFN package.
Part Context
This part belongs to the LT8350 family of Silent Switcher regulators. It shares architectural similarities with variants like the LT8350SAV but differs in current rating and automotive qualification status. The RV suffix typically denotes a specific temperature grade or package variant within the industrial line.
Replacement Considerations
LT8350SAV#WPBF is listed as a parameter equivalent. Verify if automotive qualification (AEC-Q100) is required; if so, the SA variant may be necessary despite different current ratings.
