LT1109ACS8-5#TRPBF

Overview

The LT1109ACS8-5#TRPBF is a micropower DC/DC converter and flash memory VPP generator manufactured by Analog Devices. It utilizes a boost topology to regulate output voltage within a single-output configuration. The device accepts an input voltage range from 2 V to 9 V and provides a fixed 5 V output capable of sourcing up to 1 A of current. Key electrical parameters include a static current of 360 uA and a switching frequency of 120 kHz. It operates within a temperature range of 0°C to +70°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

Integrated flash memory VPP generation capability for programming applications
Micropower operation with low quiescent current consumption
Built-in shutdown control functionality for power management

Applications

Flash memory voltage programming generation
Microprocessor DC/DC conversion
General-purpose step-up voltage regulation

Procurement Notes

Verify the specific suffix designation, as the requested model includes a TRPBF suffix indicating tape-and-reel packaging, while official documentation may primarily reference the tube-packed PBF variant. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the supply chain source provides valid manufacturer traceability for this specific Analog Devices part number to avoid counterfeit components.

Selection Notes

Select this component when a compact boost converter solution is required for generating higher voltages from low-input sources such as batteries. The integrated VPP generator feature makes it suitable for embedded systems requiring flash memory programming without external circuitry. Consider the 120 kHz switching frequency for EMI constraints and the SOIC-8 package for PCB space limitations compared to larger regulator options.

Part Context

This part belongs to the LT1109A series of micropower DC/DC converters designed by Analog Devices. It is categorized under PMIC - Power Management ICs and specifically functions as a switching voltage regulator. The series is known for combining standard DC/DC conversion with specialized flash memory VPP generation capabilities in a small footprint.
