LT1317BIS8#PBF

Overview

The LT1317BIS8#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 an adjustable output voltage from 1.24V to 30V with a maximum output current of 0.2A. The device utilizes a 600kHz PWM switching frequency and is housed in an 8-pin SOIC package. It features a typical quiescent current of 100µA and does not shift into Burst Mode operation at light loads, thereby eliminating low-frequency output ripple.

Feature Summary

Fixed-frequency PWM operation eliminates low-frequency output ripple without utilizing Burst Mode at light loads
Micropower design supports wide input voltage ranges suitable for battery-powered applications
Adjustable output voltage capability allows flexible configuration for various system requirements

Applications

Digital camera power supplies
Low noise varactor bias supply generation
Two-cell battery to 3.3V boost conversion

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific environmental restrictions such as SVHC thresholds before procurement. Ensure the ordering suffix matches the required package type and temperature grade. Request official datasheets and test reports to validate technical specifications against project requirements.

Selection Notes

Select this component when low output ripple is critical and Burst Mode efficiency trade-offs are unacceptable. The fixed 600kHz frequency aids in EMI management compared to lower frequency alternatives. Consider the 0.2A current limit and 12V maximum input voltage constraints during circuit design. Evaluate thermal performance within the commercial operating temperature range for the SOIC-8 package.

Part Context

This part belongs to the LT1317 family of micropower step-up converters. It shares core topology with variants like the LT1317BCS8 but differs in package and temperature rating. The IS8 suffix indicates a specific industrial or commercial grade variant in an 8-pin SOIC package, distinct from other pinout configurations available in the series.
