LT1934IS6-1#TRPBF

Overview

The LT1934IS6-1#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 of 300mA. Quiescent current is specified at 12µA, supporting efficient battery-powered applications. It utilizes Burst Mode operation for light-load efficiency and includes a zero-current shutdown mode. The component is housed in a TSOT-23-6 package and functions as a synchronous buck regulator.

Feature Summary

• Integrates a high-efficiency synchronous buck topology with an internal power switch
• Supports wide input voltage ranges suitable for various power sources including batteries and logic rails
• Features low quiescent current consumption to extend battery life in portable devices
• Includes a zero-current shutdown mode that disconnects the load from the input source

Applications

• Battery-powered systems requiring extended operational life
• Portable consumer electronics utilizing alkaline or lithium-ion cells
• 5V logic rail regulation from higher voltage unregulated sources
• Lead-acid battery management circuits

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the TSOT-23-6 footprint matches your PCB layout requirements. Cross-reference the datasheet for thermal performance under expected load conditions. Validate availability status directly with authorized distributors as supply levels may vary.

Selection Notes

Select this component when designing compact power solutions requiring low standby current. The adjustable output allows flexibility for various target voltages. Consider the 300mA output limit against peak load demands. The wide input range accommodates single-cell lithium or multi-cell alkaline configurations. Evaluate thermal dissipation needs given the small surface-mount package size.

Part Context

This part belongs to the LT1934 family of micropower step-down switching regulators. It shares core architecture with variants like LT1934ES6-1 but differs in package type and specific ordering suffixes. The IS6 designation identifies the TSOT-23-6 plastic package variant. This family is designed for space-constrained applications where low power consumption is critical.

Replacement Considerations

LT1934ES6-1#TRPBF is a pin-compatible alternative in the SOT-23-6 package. Verify electrical parameters and thermal characteristics match design requirements before substitution. Check for any differences in recommended external component values between package variants.
