Overview
The LT1301IS8#TRPBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It utilizes Burst Mode operation to achieve high efficiency in low-power applications. The device operates from an input voltage range of 1.8 V to 10 V and can deliver output voltages of 5 V or 12 V. It supports an output current of up to 700 mA with a quiescent current of 120 uA. The switching frequency is fixed at 155 kHz. The component is housed in an 8-SOIC package and is designed for through-hole or surface-mount installation, suitable for battery-powered systems requiring efficient voltage boosting.
Feature Summary
- Utilizes Burst Mode operation for enhanced micropower efficiency
- Capable of delivering 5V or 12V outputs from two-cell battery inputs
- Features a fixed 155 kHz switching frequency for compact external component sizing
Applications
- Flash memory power supplies
- Two-cell battery powered devices
- Micropower step-up conversion systems
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm that the IS8 variant corresponds to the SOIC-8 package type required for your PCB layout. Ensure compatibility with the 1.8 V to 10 V input range for your specific battery configuration. Cross-reference the datasheet for thermal performance requirements under maximum load conditions.
Selection Notes
Select this component when designing circuits requiring high efficiency at light loads due to its Burst Mode architecture. It is appropriate for applications where a stable 5V or 12V rail is needed from a lower voltage source like a two-cell battery. Consider the 700 mA output capability against your peak current demands. The SOIC-8 package offers a compact footprint compared to larger DIP options.
Part Context
This part belongs to the LT1301 series of micropower step-up converters. It shares core functionality with variants like LT1301IN8#PBF but differs in packaging and reel format. The IS8 designation specifies the SOIC-8 body style, while #TRPBF denotes the tape-and-reel shipping method compliant with RoHS standards.
Replacement Considerations
LT1301IS8#PBF is the tube-packaged equivalent of this component. LT1301IN8#PBF is a PDIP-8 alternative within the same family. Verify pinout compatibility before substituting between package types.
