Overview
The LT8392JFE#PBF is a synchronous 4-switch buck-boost DC/DC controller from Analog Devices, designed for high-efficiency power conversion. It supports an input voltage range of 4V to 60V and regulates output voltages from 0V to 60V. The device features a fixed switching frequency of 400kHz and includes spread spectrum modulation to reduce EMI. It operates within a temperature range of -40°C to +150°C and utilizes a TSSOP-28 package with an exposed pad for thermal management.
Feature Summary
- Synchronous four-switch topology enables efficient buck, boost, buck-boost, and SEPIC operation across wide input and output voltage ranges.
- Integrated spread spectrum modulation reduces electromagnetic interference peaks without requiring external components.
- Supports parallelable operation for increased current capability using inductor DCR current sensing.
Applications
- Industrial automation systems requiring robust power regulation
- LED lighting drivers with variable input sources
- Battery-powered equipment needing extended runtime through efficient voltage conversion
- Telecommunications infrastructure power supplies
Procurement Notes
Verify the specific suffix JFE indicates the commercial temperature grade variant when sourcing. Confirm the PBF designation ensures lead-free compliance with RoHS standards. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure authenticity and correct pinout compatibility for the TSSOP-28 package.
Selection Notes
Select this component when designing systems that require bidirectional voltage conversion between 4V and 60V inputs. It is suitable for applications demanding high efficiency across varying load conditions and low EMI profiles. Consider the exposed pad thermal requirements for PCB layout to ensure reliable operation at maximum junction temperatures.
Part Context
This controller belongs to the LT8392 family of synchronous buck-boost controllers. It shares architectural similarities with the LT8390 and LT8391 series but offers specific feature sets tailored for general-purpose and LED driver applications. The JFE#PBF variant represents a specific package and temperature grade configuration within this product line.
Replacement Considerations
Direct replacements include other models within the LT8392 family such as LT8392EFE#PBF or LT8392HFE#PBF, depending on required temperature grades. Alternative topologies may involve the LT3791 series for similar 60V synchronous buck-boost requirements.
