LT1317BCS8#TRPBF

Overview

The LT1317BCS8#TRPBF 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 720kHz switching frequency and features a typical quiescent current of 100uA. Packaged in an 8-pin SOIC N format, it is designed for commercial temperature operation between 0°C and 70°C.

Feature Summary

Fixed frequency step-up topology eliminates low-frequency output ripple at light loads by avoiding burst mode operation
Wide input voltage range supports direct connection to single-cell lithium-ion batteries or other variable sources
Micropower design ensures minimal standby consumption suitable for battery-powered applications

Applications

Digital camera power supplies
Portable instrumentation powered by single-cell lithium-ion batteries
General purpose step-up conversion from 1.5V to 12V inputs

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm that the BC grade corresponds to the required commercial temperature range specifications. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure authenticity and correct pinout configuration before integration into production designs.

Selection Notes

Select this component when low output ripple is critical at light loads, as the fixed frequency operation prevents burst mode transitions. Ensure the application requires an output current within the 0.2A limit. Consider the 720kHz switching frequency for inductor size trade-offs compared to lower frequency alternatives. Verify input voltage stability remains within the 1.5V to 12V operational window.

Part Context

This part belongs to the LT1317B family of micropower boost converters. It shares functional characteristics with variants like the LT1317BIS8 but differs in package type and temperature rating. The CS8 designation identifies the specific plastic surface-mount package variant within the broader product line.
