Overview
The LT1934IDCB#TRMPBF is a micropower step-down DC/DC converter manufactured by Analog Devices Inc. It features an internal 400mA power switch and is housed in a low-profile 1mm ThinSOT-23 package. The device supports a wide input voltage range from 3.2V to 34V, allowing it to regulate various power sources including alkaline batteries, logic rails, wall transformers, and lead-acid batteries. It operates with a fixed output voltage of 12V and provides an output current capability of 170mA.
Feature Summary
- Integrates a 400mA internal power switch for compact design
- Supports wide input voltage range from 3.2V to 34V
- Utilizes low-profile 1mm ThinSOT-23 surface mount packaging
Applications
- Regulating 4-cell alkaline battery systems
- Stepping down 5V logic rails
- Converting unregulated wall transformer outputs
- Managing lead-acid battery voltages
Procurement Notes
Verify the specific suffix #TRMPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact model LT1934IDCB#TRMPBF to avoid confusion with similar variants. Check datasheet specifications for thermal and electrical limits before integration.
Selection Notes
Select this component for applications requiring a simple buck conversion solution with minimal external components. It is suitable for battery-powered devices where space is limited due to the small package size. Consider the 400mA switch current limit when determining load requirements. Verify that the required output voltage aligns with available fixed options or external resistor settings if applicable.
Part Context
This part belongs to the LT1934 family of micropower step-down converters. It is designed for efficiency in portable electronics. The IDCB designation refers to the industrial temperature grade and the DFN/ThinSOT package type. It serves as a power management solution for converting higher input voltages to stable lower levels.
Replacement Considerations
Consult official Analog Devices documentation for direct pin-to-pin replacements. Verify compatibility regarding input voltage range, output current capacity, and package dimensions before substituting.
