Overview
The LT1934ES6#TRMPBF is a micropower step-down DC/DC converter manufactured by Analog Devices Inc. It features an internal 400mA power switch and operates within a wide input voltage range of 3.2V to 34V. The device regulates adjustable output voltages with a maximum output current of 300mA. Quiescent current is specified at 12μA, supporting efficient battery-powered systems. It includes a zero-current shutdown mode that disconnects the load from the input source. The component utilizes Burst Mode operation for high efficiency at light loads. It is housed in a TSOT-23-6 package and supports surface mount installation.
Feature Summary
- Integrates a 400mA power switch within a low-profile ThinSOT package
- Supports wide input voltage ranges from alkaline batteries to unregulated wall transformers
- Features zero-current shutdown mode to simplify power management
- Utilizes Burst Mode operation for optimized efficiency at light loads
Applications
- Battery-powered portable electronics
- Systems powered by 4-cell alkaline batteries
- Regulation of 5V logic rails
- Lead-acid battery applications
- Unregulated wall transformer power supplies
Procurement Notes
Verify the exact part number suffix against official Analog Devices documentation. Suffixes such as TRPBF or TRMPBF indicate specific packaging configurations like tape and reel. Confirm RoHS compliance status and lead-free material declarations directly from the manufacturer's datasheet or certification documents before procurement to ensure regulatory adherence.
Selection Notes
Select this component when designing circuits requiring a wide input voltage range up to 34V and low quiescent current consumption. The adjustable output voltage capability allows flexibility in system design. Ensure the required load current does not exceed the 300mA limit. Consider the TSOT-23-6 package size constraints and thermal requirements for the application environment.
Part Context
The LT1934 belongs to the LT1934 series of micropower step-down switching regulators. This family is designed for applications demanding high efficiency and low standby power. The ES6 designation typically refers to the commercial temperature grade and TSOT-23-6 package variant. It serves as a compact solution for space-constrained designs requiring reliable DC/DC conversion.
Replacement Considerations
Consult Analog Devices official cross-reference lists for verified substitutes. Direct replacements must match the TSOT-23-6 package, 300mA output current capability, and similar input voltage range. Verify pinout compatibility and control interface similarities to ensure seamless integration without circuit redesign.
