Overview
The LT8364EMSE#WPBF is a synchronous boost and SEPIC DC-to-DC converter IC manufactured by Analog Devices Inc. It features an adjustable output voltage starting from 1.6V, with a maximum switch voltage rating of 60V. The device delivers up to 4A of switch current and operates within a switching frequency range of 300kHz to 2MHz. It supports an input voltage range from 2.8V to 60V and includes integrated synchronous rectification. The component is housed in a 16-TFSOP package with dimensions of 0.118 inches (3.00mm) width and twelve leads, including an exposed pad for thermal management.
Feature Summary
- Integrates synchronous rectification for improved efficiency in boost and SEPIC topologies
- Supports wide input voltage ranges suitable for battery-powered applications
- Features adjustable output voltage control for flexible system design
Applications
- Battery-powered portable electronics requiring step-up conversion
- Industrial systems utilizing SEPIC configurations for varying input sources
- Automotive electronics needing high-voltage regulation from lower supply rails
Procurement Notes
Verify the specific suffix WPBF indicates lead-free compliance and RoHS standards when sourcing. Confirm the MSOP-EP package variant matches your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for the Analog Devices manufacturing origin. Cross-reference the date code against current product change notifications to verify material consistency.
Selection Notes
Select this component when designing circuits that require both boost and SEPIC capabilities within a single controller. Consider the 4A switch current limit for power handling needs. Evaluate the 300kHz to 2MHz frequency range against EMI constraints and external component sizing requirements. Ensure the 60V switch voltage rating accommodates peak transient voltages in the application environment.
Part Context
This part belongs to the LT8364 family of high-voltage synchronous converters. It shares architectural similarities with other Analog Devices regulators but is distinct in its combined boost/SEPIC functionality. The EMSE#WPBF designation specifies the commercial temperature grade and surface-mount packaging format used in modern compact power designs.
Replacement Considerations
Direct substitutes may include other Analog Devices high-voltage synchronous converters with similar current ratings. Verify pin compatibility and thermal performance before swapping. Check datasheets for equivalent switching frequencies and input voltage ranges to ensure circuit stability without redesign.
