LT1317BCS8#PBF

Overview

The LT1317BCS8#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 features a typical quiescent current of 100µA and a switching frequency of 600kHz. It is housed in an 8-pin SOIC package and supports commercial operating temperatures from 0°C to +70°C.

Feature Summary

Fixed-frequency PWM operation eliminates low-frequency output ripple without utilizing Burst Mode at light loads
Micropower design enables extended battery life through low quiescent current consumption
Wide input voltage range accommodates single-cell lithium-ion or alkaline battery sources

Applications

Digital camera power supplies
Two-cell battery to 3.3V boost converters
Lithium-ion to 8.2V DC/DC conversion circuits

Procurement Notes

Verify the specific suffix CS8 corresponds to the SOIC-8 package variant when sourcing. Confirm RoHS compliance status directly with the manufacturer or authorized distributors as regulatory details may vary by production batch. Ensure the ordering part number matches the exact temperature grade and packaging requirements for your assembly process.

Selection Notes

Select this component for applications requiring a simple boost topology with minimal external components. It is suitable where low noise output is critical due to the absence of burst mode operation. Consider the 0.2A current limit and 600kHz switching frequency when designing the inductor and capacitor values for your specific power requirements.

Part Context

This part belongs to the LT1317 series of micropower switching regulators. The 'B' suffix typically denotes a specific performance grade or temperature range within the family. It shares functional similarities with other LT1317 variants but differs in package type and potentially thermal characteristics compared to MSOP or IS8 versions.
