Overview
The LT8606EMSE#TRPBF is a synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5V to 42V and delivers up to 350mA of output current. The device features a low quiescent current of 2.5µA and supports switching frequencies from 200kHz to 2.2MHz. It provides adjustable output voltage within a single-output configuration. The component is housed in an MSOP-10 package and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Synchronous buck topology for efficient power conversion
- Ultra-low quiescent current operation for battery-powered applications
- Wide input voltage range supporting various supply sources
- Adjustable output voltage via external resistor network
Applications
- Portable instrumentation powered by single-cell lithium batteries
- Industrial field devices requiring high efficiency at light loads
- Embedded systems with wide input voltage variations
- Battery-operated consumer electronics
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. or its authorized predecessor Linear Technology. Ensure the part matches the MSOP-10 footprint and electrical specifications provided in the official datasheet before integration into production designs.
Selection Notes
Select this component for designs requiring a compact solution with minimal standby power consumption. The 350mA output capability suits low-power microcontrollers and sensors. Consider the 2.5µA quiescent current for extended battery life requirements. Verify that the required output voltage falls within the adjustable range supported by the external feedback resistors.
Part Context
This part belongs to the LT8606 family of micropower synchronous step-down regulators. It shares core architectural features with other members like the LT8606B, differing primarily in package options and minor performance variations. The EMSE designation specifies the MSOP-10 surface-mount package variant suitable for space-constrained PCB layouts.
Replacement Considerations
LT8606EMSE#PBF is a tube-packaged version of the same functional device. LT8606BIDC#TRMPBF offers identical electrical performance in a DFN-8 package.
