LT1317IS8#PBF

Overview

The LT1317IS8#PBF is a micropower, fixed-frequency step-up DC/DC converter manufactured by Analog Devices Inc. It operates over a wide input voltage range of 1.5V to 12V and provides a single output up to 30V with a maximum output current of 500mA. The device utilizes a 600kHz PWM switching frequency and features an SOIC-8 surface-mount package. It includes shutdown functionality and maintains operation within a temperature range of 0°C to +70°C.

Feature Summary

Fixed 600kHz PWM switching frequency for consistent noise spectrum
Micropower architecture designed for battery-operated applications
Integrated shutdown pin for extended battery life management

Applications

Low noise varactor bias supplies
Digital camera power systems
Two-cell battery to 3.3V boost converters

Procurement Notes

Verify the specific suffix IS8 against official Analog Devices documentation to confirm the industrial temperature grade and SOIC-8 package variant. Ensure compatibility with system thermal requirements and PCB layout constraints associated with the specified footprint before finalizing procurement orders.

Selection Notes

Select this component when a fixed switching frequency is required to simplify EMI filtering compared to burst-mode alternatives. It is suitable for designs prioritizing low output ripple at light loads over maximum light-load efficiency, particularly in space-constrained portable electronics requiring stable voltage regulation from varying input sources.

Part Context

This part belongs to the LT1317 family of micropower boost converters. It shares core topology with variants like LT1317CS8 and LT1317BIS8 but differs in temperature rating and package specifications. The IS8 designation indicates an industrial temperature range and specific physical packaging distinct from commercial or military grades.

Replacement Considerations

LT1317CS8#PBF and LT1317BIS8#PBF are related family members. Verify temperature ranges and package dimensions before substitution as functional parameters may vary between commercial, industrial, and other grade designations within the same series.

FAQ

Does the LT1317IS8#PBF use Burst Mode operation?

No, the LT1317B variant does not shift into Burst Mode at light loads, which eliminates low-frequency output ripple at the expense of light-load efficiency.
