Voltage Regulators - DC DC Switching Regulators datasheet and documents for LT1054IDWR

LT1054IDWR

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054IDWR 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. Designed for industrial applications, it functions reliably between -40°C and +85°C. Packaged in a 16-SOIC surface-mount format, this component supports both boost and buck topologies for efficient power management.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated switched-capacitor topology eliminates the need for external inductors
Built-in linear regulator provides stable output voltage regulation
Low quiescent current consumption enhances system efficiency
Supports flexible boost and buck conversion configurations

Voltage Regulators - DC DC Switching Regulators Applications

Portable battery-powered instrumentation
Industrial control systems requiring isolated or inverted rails
Communication equipment needing negative voltage generation
Embedded systems with space-constrained PCB layouts

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'IDWR' against the official Texas Instruments datasheet to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with existing PCB footprints for the 16-SOIC package. Cross-reference RoHS compliance status with current manufacturer declarations. Confirm availability through authorized distributors to avoid counterfeit components. Validate thermal performance requirements for the intended operating environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select the LT1054IDWR when inductor-free solutions are required for moderate current loads up to 100 mA. Consider the 25 kHz switching frequency for EMI-sensitive designs where lower frequencies are acceptable. Evaluate the 100 uA static current against standby power constraints. Compare the SOIC-16 package dimensions with available board space. Assess the -40°C to +85°C industrial temperature range against operational extremes.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1054 series represents a family of switched-capacitor converters known for simplicity and compactness. The IDWR variant specifically denotes the industrial temperature grade housed in a 16-pin Small Outline Integrated Circuit package with reel packaging. This part complements Texas Instruments' broader portfolio of power management integrated circuits designed for versatile DC-DC conversion tasks without magnetic components.
