Overview
The LT1302CS8#PBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates from an input voltage range of 2 V to 8 V and delivers up to 2 A output current. The device features a fixed 5 V output option with adjustable capability, utilizing a boost topology. Key electrical parameters include a switching frequency of 400 kHz and a quiescent current of 200 uA. It functions within a temperature range of 0°C to +70°C and is housed in an SOIC-8 surface-mount package.
Feature Summary
- Automatic transition between Burst Mode operation at light loads and current mode operation at heavy loads to maintain high efficiency across wide output current ranges.
- Micropower design optimized for battery-powered applications with low quiescent current consumption.
- Integrated shutdown pin for power management control.
Applications
- Single-cell lithium-ion or alkaline battery powered systems requiring voltage step-up
- Portable handheld devices needing efficient DC/DC conversion
- Battery-operated instrumentation and sensors
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence as per Analog Devices standards. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision date to ensure compatibility with your design constraints.
Selection Notes
Select this component when a fixed 5 V output is required from a single-cell battery source. The 2 A output current capability supports moderate load demands. Consider the 400 kHz switching frequency for inductor size trade-offs. Verify that the SOIC-8 package is suitable for your assembly process compared to through-hole alternatives like the CN8 variant.
Part Context
This part belongs to the LT1302 series of micropower step-up converters. It shares functional similarities with other variants such as LT1302CN8#PBF but differs in package type (SOIC-8 vs PDIP) and potentially thermal characteristics. The series is designed for high efficiency in portable applications.
Replacement Considerations
LT1302CN8#PBF offers identical electrical performance in a PDIP-8 through-hole package. LT1302CS8#TRPBF provides the same SOIC-8 package in tape-and-reel format for automated assembly. Verify pinout compatibility before substitution.
