Overview
The LT1110CS8-12#TRPBF is a micropower DC-DC converter manufactured by Analog Devices Inc. It operates with supply voltages ranging from 1.0V to 30V and supports both step-up and step-down conversion modes. The device delivers a fixed output voltage of 12V with an internal power switch capable of handling up to 1A. Key electrical parameters include a quiescent current of 300µA, a switching frequency of 70kHz, and an operating temperature range from -40°C to +85°C. It is housed in an 8-pin SOIC package.
Feature Summary
- Requires only three external components for operation
- Integrated low-battery detector comparator
- On-chip user-adjustable current limit
- Internal 1A power switch
Applications
- Single cell battery powered systems
- Remote monitoring equipment
- Portable instrumentation
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the fixed 12V output variant. Check RoHS compliance status as required by your manufacturing standards. Validate the package type is SOIC-8.
Selection Notes
Select this component for applications requiring minimal external parts count and low standby current. It is suitable for designs where input voltage varies significantly or requires buck/boost capability. Consider the 70kHz frequency for inductor size trade-offs. Verify that the 1A peak switch current meets load requirements.
Part Context
This part belongs to the LT1110 family of micropower DC-DC converters. It shares functional similarities with the LT1111 but offers different optimization for specific input ranges. The CS8-12 designation specifies the commercial temperature grade and fixed 12V output. The #TRPBF suffix denotes the reel packaging format.
Replacement Considerations
LT1110CS8-12#PBF is the tube-packaged equivalent. LT1111CS8-12#PBF is a related device with similar functionality but potentially different efficiency characteristics at higher input voltages.
