Overview
The LT8337JV#PBF is a synchronous step-up DC-to-DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7 V to 28 V and delivers up to 5 A output current at a maximum output voltage of 28 V. The device features a low quiescent current of 15 uA and supports adjustable switching frequencies from 300 kHz to 3 MHz. It is housed in a 16-pin LQFN package, rated for operation between -40°C and +150°C, and includes shutdown functionality.
Feature Summary
- Synchronous boost topology for high efficiency
- Silent Switching architecture to minimize EMI
- Wide input voltage range supporting single-cell lithium batteries
- Integrated power switch and control logic
Applications
- Battery-powered portable equipment
- Industrial sensor nodes
- Medical instrumentation
- Automotive electronics
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the LQFN-16 package dimensions against your PCB footprint requirements. Check current availability status as supply may be restricted. Ensure thermal management design accounts for the 150°C maximum junction temperature rating during operation.
Selection Notes
Select this component when high output current capability near 5 A is required alongside wide input voltage flexibility. Compare against LT8336 if lower current suffices, or LT8338 for smaller packaging needs. Consider the 300 kHz to 3 MHz frequency range for optimizing external inductor size versus efficiency trade-offs in your specific application environment.
Part Context
This part belongs to the LT833x family of Silent Switcher regulators from Analog Devices. These devices are designed for applications requiring low electromagnetic interference without external shielding. The series emphasizes compact solutions for space-constrained designs while maintaining robust performance across varying load conditions and temperatures.
Replacement Considerations
LT8336JV#PBF offers similar functionality but with reduced output current capacity. LT8338JMSE#PBF provides comparable features in a smaller MSOP-10 package. Verify pin compatibility and thermal characteristics before substituting these alternatives in existing designs.
