Overview
The LT1976BEFE#TRPBF is a monolithic step-down switching regulator from Analog Devices Inc., designed for high-voltage applications with an input voltage range up to 60V. It delivers a continuous output current of 1.5A at a fixed switching frequency of 200kHz. The device features an integrated 0.2Ω power switch and supports adjustable output voltages starting from 1.25V up to 55.2V. Housed in a 16-TSSOP package with an exposed pad, it operates within a junction temperature range of -40°C to 125°C.
Feature Summary
- High-voltage operation capability accepting input voltages up to 60V
- Integrated high-efficiency 1.5A power switch with low on-resistance
- Fixed 200kHz switching frequency for optimized passive component size
- Adjustable output voltage regulation starting from 1.25V
Applications
- Battery charging systems
- LED lighting drivers
- Portable electronic devices requiring regulated power
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the BEFE variant specifications against the official LT1976/LT1976B datasheet to ensure compatibility with your thermal and electrical requirements. Check for RoHS compliance documentation provided by Analog Devices Inc. prior to final procurement decisions.
Selection Notes
Select this component for designs requiring high input voltage tolerance and moderate output current. The 200kHz frequency balances efficiency and component size. Ensure the PCB layout accommodates the 16-TSSOP-EP package for adequate thermal dissipation. Compare against the LT1976IFE variant if different packaging or temperature grades are required.
Part Context
This part belongs to the LT1976 family of high-voltage buck regulators. It shares core architecture with the LT1976B but may differ in specific manufacturing lot or packaging details defined by the suffix. The series is characterized by its robust internal switch and wide input voltage range, suitable for industrial and automotive environments.
Replacement Considerations
LT1976IFE#TRPBF is a pin-compatible alternative with similar electrical characteristics but potentially different packaging or temperature grade specifications. Verify thermal performance and exact parameter tolerances before substitution.
