Voltage Regulators - DC DC Switching Regulators datasheet and documents for LT1054IDW

LT1054IDW

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054IDW is a switched-capacitor voltage converter with an integrated regulator, manufactured by Texas Instruments. It operates within an input voltage range of 3.5 V to 15 V and delivers a regulated output current of 100 mA. The device features a switching frequency of 25 kHz and a typical static current of 100 uA. It supports both boost and buck topologies and provides a fixed -5 V output. The component is housed in a 16-SOIC package designed for surface mount installation. It functions reliably across an operating temperature range from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a switched-capacitor charge pump with a linear regulator for stable voltage conversion
Supports flexible circuit configurations including step-up (boost) and step-down (buck) operations
Provides low quiescent current operation suitable for battery-powered applications

Voltage Regulators - DC DC Switching Regulators Applications

Generating negative supply rails from positive sources
Powering RS-232 interface circuits
Providing isolated or shifted voltage levels in data acquisition systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix IDW confirms the industrial temperature grade (-40°C to +85°C) and SOIC-16 package variant. Confirm RoHS compliance status through the official datasheet as manufacturing revisions may affect material declarations. Ensure the ordering part number matches the exact manufacturer designation to avoid compatibility issues with existing PCB footprints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution for generating negative voltages or level shifting is required without inductors. The 100 mA output current limits suitability for high-power loads. Consider the 25 kHz switching frequency for EMI constraints compared to higher-frequency alternatives. Verify that the external capacitor requirements align with the available board space and budget.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1054 belongs to a family of switched-capacitor regulators originally developed by Linear Technology and now produced by Texas Instruments. This series is known for eliminating the need for bulky inductors in low-to-medium power applications. The IDW suffix specifically denotes the industrial temperature range and plastic small-outline package, distinguishing it from commercial or military variants.
