Overview
The LT8494IFE#TRPBF is a monolithic switching regulator from Analog Devices, packaged in a 20-lead TSSOP with an exposed pad. It supports adjustable switching frequencies ranging from 250 kHz to 1.5 MHz and operates with a quiescent current of less than 7 µA during operation. The device accepts input voltages between 1 V and 32 V and provides a single adjustable output voltage range from 1.202 V to 70 V. Designed for automotive applications, it features a shutdown mode that reduces quiescent current to 0.3 µA when the SWEN pin is low.
Feature Summary
- Configurable as SEPIC, boost, or flyback converter topologies
- Integrated charge pump switches for high-voltage gate driving
- Adjustable switching frequency up to 1.5 MHz
- Ultra-low shutdown current via SWEN control
Applications
- Automotive power systems requiring wide input/output ranges
- Battery-powered equipment needing extended standby life
- Industrial control circuits utilizing SEPIC or boost configurations
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging rather than tube packaging. Confirm the component meets AEC-Q100 automotive qualification standards if required for your application. Ensure the ordering part number matches the exact package type and temperature grade specified in the official datasheet.
Selection Notes
Select this component when designing circuits that require flexible topology options including SEPIC, boost, or flyback. It is suitable for applications demanding low standby power consumption through the SWEN pin feature. Consider the 20-lead TSSOP package constraints and thermal requirements associated with the exposed pad design.
Part Context
This part belongs to the LT8494 family of wide input and output range DC/DC converters. It shares functional similarities with other Automotive-grade regulators but is distinct due to its integrated charge pump and configurable topology capabilities. The #TRPBF suffix specifically denotes the reel packaging format for automated assembly.
Replacement Considerations
LT8494EFE#PBF offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel. Verify that the change in physical packaging does not impact your manufacturing process or board layout requirements.
