LT1111CS8#TRPBF

Overview

The LT1111CS8#TRPBF is a micropower DC/DC converter manufactured by Analog Devices Inc., housed in an 8-SOIC package. It supports both boost and buck topologies with an adjustable output voltage ranging from 1.25V to 50V (switch). The device delivers a switch current of 800 mA to 1.5A and operates within an input voltage range of 2V to 30V. Key electrical parameters include a switching frequency of 72 kHz, a quiescent current of 300 uA, and an operating temperature range of 0°C to +70°C.

Feature Summary

Supports both step-up (boost) and step-down (buck) voltage conversion topologies
Features micropower operation with low quiescent current consumption
Provides adjustable output voltage capability across a wide range

Applications

Battery-powered portable equipment requiring efficient voltage regulation
Systems needing positive or negative supply rails from a single source
General-purpose micropower DC/DC conversion tasks

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component for applications requiring flexible buck-boost functionality in a compact SOIC-8 footprint. Consider the 72 kHz switching frequency and 300 uA quiescent current for efficiency requirements. Verify that the 2V to 30V input range aligns with the system power supply constraints.

Part Context

This part belongs to the LT1111 series of micropower DC/DC converters from Analog Devices. It is designed for low-power applications where space and energy efficiency are critical. The device integrates the necessary control circuitry for efficient voltage transformation in a small surface-mount package.
