Overview
The LT1934IS6#TRPBF is a micropower step-down DC/DC converter manufactured by Analog Devices Inc. It features an internal power switch and operates within an input voltage range of 3.2V to 34V. The device provides an adjustable output voltage with a maximum output current capability of 300mA. Quiescent current consumption is specified at 12µA, supporting efficient battery-powered applications. The switching frequency is externally adjustable. It is housed in a TSOT-23-6 package and supports operation across a temperature range from -40°C to +85°C.
Feature Summary
- Integrates a high-efficiency internal power switch for compact step-down conversion
- Features Burst Mode operation to minimize quiescent current during light loads
- Includes zero-current shutdown mode to disconnect the load from the input source
- Supports wide input voltage ranges suitable for various power sources
Applications
- Battery-powered systems requiring low standby current
- Regulation of unregulated wall transformers
- Power management for lead-acid batteries
- Step-down conversion from 5V logic rails
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official documentation prior to integration. Ensure the supplier provides valid traceability data. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and avoid counterfeit components.
Selection Notes
Select this component for designs requiring a small footprint and low quiescent current. The adjustable switching frequency allows optimization for external component size versus efficiency trade-offs. Verify that the required output current does not exceed the internal switch limits under all operating conditions and thermal constraints.
Part Context
This part belongs to the LT1934 series of micropower step-down switching regulators. The series is characterized by its ability to regulate diverse power sources while maintaining low power consumption. The IS6 designation specifies the industrial temperature grade and the TSOT-23-6 package type, distinguishing it from other variants in the family.

FAQ
How does the LT1934 handle light load conditions?
It utilizes Burst Mode operation to reduce quiescent current significantly when the load demand is low, thereby improving overall system efficiency.
What is the function of the shutdown pin?
The shutdown feature places the device in a zero-current state, effectively disconnecting the load from the input source to conserve energy in battery-operated applications.
