DC DC Switching Controllers datasheet and documents for LTC3872ETS8#TRPBF
DC DC Switching Controllers Overview
The LTC3872ETS8#TRPBF is a constant frequency current mode boost DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.75V to 9.8V and supports output voltages up to 60V. The device features a fixed switching frequency of 550kHz and a low operating supply current of 250µA. Packaged in a TSOT-23-8 surface-mount case, it functions across a temperature range of -40°C to +85°C. Key control characteristics include cycle-by-cycle current limiting, enable functionality, and soft start capabilities.
DC DC Switching Controllers Feature Summary
- No RSENSE current mode control architecture
- Integrated soft start and cycle-by-cycle current limit
- Low quiescent supply current for efficiency
DC DC Switching Controllers Applications
- Battery-powered portable equipment
- Industrial point-of-load regulation
- Automotive subsystem power supplies
DC DC Switching Controllers Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging with lead-free finish. Confirm the ETS8 designation matches the required TSOT-23-8 thin package variant. Ensure RoHS compliance documentation aligns with project requirements before finalizing procurement orders.
DC DC Switching Controllers Selection Notes
Select this component when a compact boost controller is needed without external sense resistors. The TSOT-23-8 package suits space-constrained designs. Verify that the 550kHz frequency meets EMI constraints and that the 2.75V minimum input voltage aligns with the source battery profile.
DC DC Switching Controllers Part Context
This part belongs to the LTC3872 family of no RSENSE current mode boost controllers. It shares architectural similarities with other members like the LTC3872EDDB but differs in package type. The ETS8 suffix specifically denotes the TSOT-23-8 thin outline small transistor package suitable for high-density PCB layouts.
DC DC Switching Controllers Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Analog Devices boost controllers based on pin compatibility and electrical specifications if direct substitution is required.
