Overview
The LT1303IS8-5#PBF is a micropower high-efficiency step-up DC/DC converter manufactured by Analog Devices Inc. It operates in boost topology with a fixed 5V output and supports an input voltage range of 1.8V to 6V. The device delivers up to 200mA output current while consuming only 120µA quiescent current. It features a 155kHz switching frequency and includes a low-battery detector with open-collector output. The component is housed in an 8-lead SOIC package and functions within a temperature range of 0°C to +70°C.
Feature Summary
- Integrates a low-battery detector providing an open-collector output signal when input voltage drops below a preset threshold.
- Utilizes Step Mode operation to achieve high efficiency in small, low-voltage battery-powered systems.
- Includes a shutdown pin that reduces quiescent current consumption to 10µA for extended battery life.
Applications
- Small, low-voltage battery-operated systems
- Micropower high-efficiency step-up DC/DC conversion
- Portable electronic devices requiring regulated 5V supply from lower input voltages
Procurement Notes
Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the IS8 variant corresponds to the industrial temperature grade (-40°C to +85°C) if required, as datasheets may list operational ranges differently than the specific part number's qualified range. Ensure the SOIC-8 footprint matches your PCB design constraints before procurement.
Selection Notes
Select this component when a fixed 5V output is required from inputs between 1.8V and 6V. It is suitable for applications prioritizing low quiescent current (120µA active, 10µA shutdown) over higher output currents. Compare against the adjustable LT1303 version if variable output voltage is needed, or consider the LT1305/LT1302 for higher current demands exceeding 200mA.
Part Context
This part belongs to the LT1303 series of micropower DC/DC converters. The 'IS8' designation specifies the Industrial temperature range and SOIC-8 package. The '-5' suffix indicates the fixed 5V output configuration. This series is designed to replace linear regulators in battery applications to extend operating time through higher efficiency step-up conversion.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. For higher output current requirements, the LT1305 or LT1302 are referenced as alternatives within the same product family.
