Overview
The LT1302CN8#PBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates from an input voltage range of 2V to 8V and provides an adjustable output voltage with a maximum output current of 2A. The device features a switching frequency of 400 kHz and a typical quiescent current of 200 uA. It utilizes a boost topology and is housed in an 8-pin PDIP package designed for through-hole mounting. The component supports a shutdown function and operates within a temperature range of 0°C to +70°C.
Feature Summary
- Automatic shifting between Burst Mode operation at light loads and current mode operation at heavy loads to maintain high efficiency across a wide output current range
- Capable of operating from supply voltages as low as 2V, suitable for single-cell battery applications
- Includes a shutdown feature for power management
Applications
- Single cell to 5V or 12V step-up conversion circuits
- Battery-powered portable devices requiring micropower regulation
- General purpose DC/DC boosting applications
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS status against the manufacturer's latest documentation. Confirm the PDIP-8 package type matches your PCB footprint requirements. Ensure the 2A output current rating aligns with your thermal design capabilities. Check for any recent product change notifications regarding pinout or electrical specifications before finalizing procurement.
Selection Notes
Select this component when a micropower boost converter is needed with an input voltage starting at 2V. The adjustable output allows flexibility for various voltage rails. Consider the 400 kHz switching frequency for inductor size trade-offs. The PDIP-8 package is suitable for prototyping or through-hole designs rather than high-density surface mount applications. Verify that the 2A peak current capability meets the load requirements without exceeding thermal limits.
Part Context
The LT1302 series consists of micropower step-up DC/DC converters designed for high efficiency over a wide output current range. The CN8 variant specifically denotes the PDIP-8 package configuration. This family is characterized by its ability to operate from low input voltages and automatically switch between burst mode and current mode control to optimize performance under varying load conditions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Analog Devices documentation for potential cross-references or updated revisions within the LT1302 family.
