Overview
The LT8607BHDC#TRMPBF is a synchronous step-down regulator from Analog Devices Inc., designed for high-efficiency power conversion. It supports an input voltage range of 3V to 42V and delivers up to 750mA output current. The device features adjustable switching frequencies between 200kHz and 2.2MHz, allowing optimization for size or efficiency. It operates within a junction temperature range of -40°C to 150°C and utilizes an 8-lead DFN package with an exposed pad for thermal management.
Feature Summary
- Synchronous buck topology ensures high efficiency across the load range
- Wide 3V to 42V input voltage capability accommodates various supply rails
- Adjustable switching frequency allows design flexibility for component sizing
- Integrated thermal performance via exposed pad package design
Applications
- Industrial control systems requiring robust power regulation
- Automotive electronics operating under wide voltage variations
- Point-of-load conversion in distributed power architectures
- Battery-powered equipment needing extended runtime efficiency
Procurement Notes
Verify the specific suffix TRMPBF indicates tape-and-reel packaging with cut-tape availability options. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the 8-DFN footprint matches your PCB layout constraints. Check for any recent product change notices affecting pinout or electrical characteristics.
Selection Notes
Select this component when input voltages exceed standard 5V or 12V regulators while maintaining moderate current needs. The adjustable frequency feature is critical if electromagnetic interference must be shifted away from sensitive bands. Consider the 750mA limit against peak load requirements including transient spikes. Evaluate thermal dissipation capabilities based on ambient conditions and board copper area.
Part Context
This part belongs to the LT8607 family of high-voltage synchronous buck regulators. It shares core architecture with variants like LT8607BDFN and LT8607HDC but differs in package type and reel configuration. The family targets applications demanding high input voltage tolerance and compact form factors. Analog Devices designs these ICs for reliable operation in harsh industrial and automotive environments.
Replacement Considerations
LT8607HDC#TRPBF offers similar electrical specifications with reel packaging instead of cut-tape. LT8607EDC#TRMPBF provides the same functionality in an 8-lead DFN package variant. Verify pin compatibility and thermal resistance values when substituting. Ensure switching frequency ranges overlap to maintain existing filter designs.
