LT1110CS8#TRPBF

Overview

The LT1110CS8#TRPBF is a micropower DC-DC converter manufactured by Analog Devices Inc., housed in an 8-pin SOIC package. It operates with input voltages ranging from 1 V to 30 V and delivers a maximum output current of 1 A. The device supports both boost and buck topologies with adjustable or fixed output voltages. Key electrical parameters include a quiescent current of 300 µA and a switching frequency of 70 kHz. It functions within a temperature range of 0°C to +70°C.

Feature Summary

• Supports step-up and step-down conversion modes using only three external components
• Features an on-chip auxiliary gain block for low-battery detection or linear post-regulation
• Includes internal user-adjustable current limit protection
• Operates at very low supply voltages starting from 1.0 V

Applications

• Battery-powered remote monitoring systems
• Laser diode drivers requiring stable power from single-cell sources
• Portable electronic devices with strict power consumption constraints
• Industrial control circuits needing isolated or regulated supplies from varying input rails

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Analog Devices documentation prior to procurement. Ensure the supplier provides valid traceability records. Check for any obsolescence notices or lifecycle changes directly from the manufacturer before finalizing purchase orders.

Selection Notes

Select this component when designing circuits that require high efficiency from low-voltage sources like single lithium cells. Consider the 70 kHz switching frequency for balancing component size against noise. Evaluate the need for the internal comparator if battery monitoring is required. Compare against the LT1111 if input voltages consistently exceed 3 V, as it may offer better performance for step-down applications.

Part Context

This part belongs to the LT1110 series of micropower DC-DC converters. It shares functional similarities with the LT1111 but differs in input voltage range and recommended application scenarios. The CS8 designation specifies the commercial temperature grade and SOIC-8 package type. It is distinct from comparator or amplifier variants within the broader LT product line.

Replacement Considerations

LT1110CS8#PBF is a tube-packaged equivalent with identical electrical specifications.
