Overview
The LT1308CS8#TRPBF is a micropower DC/DC converter featuring Boost and SEPIC topologies, manufactured by Analog Devices Inc. It operates with an input voltage range of 1V to 10V and provides an adjustable output voltage from 1.22V to 34V. The device supports a switch current of 2A at a fixed switching frequency of 600kHz. Packaged in an 8-SOIC (3.90mm wide) surface-mount format, it functions within a temperature range of -40°C to +85°C. This component integrates high-efficiency power conversion capabilities suitable for battery-powered applications requiring flexible voltage regulation.
Feature Summary
- Integrates Boost and SEPIC converter topologies for versatile step-up and step-down/buck-boost operation
- Supports low input voltage starting at 1V, enabling efficient power management from single-cell sources
- Delivers up to 2A switch current capability for moderate load requirements
- Features adjustable output voltage control allowing customization across a wide range
Applications
- Battery-powered portable equipment requiring extended runtime
- Systems needing voltage boosting from low-voltage sources
- Applications requiring both step-up and step-down voltage regulation from a single supply
- Industrial sensors operating on limited energy budgets
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the commercial grade temperature range (-40°C to +85°C) matches your environmental requirements. Ensure input voltage constraints are respected to maintain stable operation. Cross-reference the datasheet for thermal dissipation needs in SOIC-8 packages under maximum load conditions.
Selection Notes
Select this component when design requirements demand a single-inductor solution for both boost and SEPIC functionalities. It is appropriate for designs where input voltages may drop below typical regulator thresholds but require higher output levels. Consider the 600kHz switching frequency for passive component size trade-offs. Evaluate the 2A limit against peak load demands to ensure adequate headroom.
Part Context
This part belongs to the LT1308 series of micropower DC/DC converters. It shares the core topology and performance characteristics with other variants in the family, differentiated primarily by package type and temperature rating. The CS8 designation specifies the commercial temperature range and SOIC-8 footprint, distinguishing it from industrial or wider-package alternatives.
Replacement Considerations
LT1308AIS8#TRPBF offers the same electrical specifications but with an extended industrial temperature range (-40°C to +125°C). Verify if the broader thermal tolerance is necessary for your application environment before substituting.
