Overview
The LT1308BCF is a micropower, fixed-frequency step-up DC/DC converter from Analog Devices Inc. It operates over a 1V to 10V input voltage range and integrates an internal switch. The device supports boost and SEPIC topologies with one adjustable output. It features a switching frequency of 600kHz and delivers up to 2A output current. The component is housed in a 14-lead TSSOP package and operates within a temperature range of 0°C to 70°C.
Feature Summary
- Integrates a high-performance monolithic power switch for efficient energy conversion
- Supports flexible boost and SEPIC topology configurations for various voltage requirements
- Operates with low input voltage starting at 1V for extended battery life applications
Applications
- Portable electronic devices requiring step-up voltage regulation
- Battery-powered systems utilizing single-cell lithium or alkaline sources
- Industrial control modules needing isolated or boosted power rails
Procurement Notes
Verify the specific suffix (PBF vs TRPBF) against your manufacturing requirements, as it denotes lead-free through-hole or tape-and-reel packaging respectively. Confirm that the component status is acceptable for new designs, as some listings indicate obsolete status. Ensure the 14-TSSOP footprint matches your PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a compact solution is needed for boosting low input voltages up to higher levels with moderate current demands. The fixed 600kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the thermal performance within the 14-TSSOP package if operating near maximum current limits in enclosed spaces.
Part Context
This part belongs to the LT1308 family of micropower switching regulators designed by Linear Technology, now part of Analog Devices. These converters are engineered for space-constrained applications where efficiency and low quiescent current are critical. The BC grade indicates specific electrical parameter tolerances suitable for general-purpose industrial and commercial use cases.
Replacement Considerations
Check for direct pin-compatible substitutes within the LT1308 series such as LT1308ACF or LT1308CCF if availability is an issue. Verify that any alternative maintains the same 600kHz switching frequency and 2A current capability to ensure circuit compatibility without redesigning the feedback network.
