Overview
The LT1307BIS8#PBF is a micropower, fixed-frequency PWM DC/DC converter manufactured by Analog Devices Inc. It operates from an input voltage range of 1V to 5V and provides an adjustable output voltage up to 30V. The device features a 600kHz switching frequency and supports boost topology with a maximum switch current of 100mA. It utilizes an 8-pin SOIC package and includes shutdown functionality. The component is designed for high efficiency across a broad load range, maintaining performance in applications requiring low quiescent current.
Feature Summary
- Implements true current mode PWM control architecture for single-cell supply operation
- Integrates automatic power-saving Burst Mode shifting at light loads to maintain efficiency
- Provides fixed-frequency operation without transitioning to discontinuous modes under normal conditions
Applications
- Single-cell battery powered microprocessor systems
- Portable instrumentation requiring low quiescent current
- General-purpose step-up conversion from 1V to 5V sources
Procurement Notes
Verify the specific suffix 'IS8' against official Analog Devices documentation to confirm temperature grade and package variant. Ensure compatibility with system thermal requirements for the SOIC-8 package. Cross-reference datasheet revisions to validate pinout and electrical characteristics before integration into final designs.
Selection Notes
Select this component when designing circuits that require efficient step-up conversion from very low input voltages such as single lithium cells. It is suitable for applications prioritizing steady-state regulation over burst-mode noise performance. Consider the 100mA switch current limit when sizing external inductors and ensuring adequate thermal dissipation within the SOIC-8 footprint constraints.
Part Context
This part belongs to the LT1307 family of micropower DC/DC converters. It shares architectural similarities with variants like LT1307IS8#PBF but may differ in specified operating temperature ranges or manufacturing lot specifications. The series is characterized by its ability to deliver stable PWM regulation directly from single-cell supplies.
Replacement Considerations
LT1307IS8#PBF serves as a primary functional substitute within the same product family. Verify temperature range specifications and package marking differences between the B-grade and standard industrial grades before substitution.
