Voltage Regulators - DC DC Switching Regulators datasheet and documents for LT1054CDW

LT1054CDW

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054CDW is a switched-capacitor voltage converter with an integrated regulator, manufactured by Texas Instruments. It operates within an input voltage range of 3.5V to 15V and provides a single adjustable or fixed output up to 26.4V. The device delivers a maximum output current of 100mA and functions at a switching frequency of 25kHz. Packaged in a 16-SOIC surface-mount case, it supports both positive and negative output configurations. The component is designed for industrial temperature ranges, specifically from 0°C to 70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a charge pump topology with a linear regulator for stable voltage conversion.
Supports flexible output configurations including boost, buck, and inverting modes.
Features an adjustable output voltage capability alongside fixed options.

Voltage Regulators - DC DC Switching Regulators Applications

Power supply systems requiring isolated or inverted voltage rails.
Interface circuits needing dual polarity power sources from a single supply.
Battery-powered devices utilizing charge pump technology for voltage step-up.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., CDW vs CDWG4) against the manufacturer's official datasheet to ensure correct temperature rating and RoHS compliance status. Confirm package dimensions match the 16-SOIC specification. Check current production status as variants may be discontinued or replaced by newer series components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a combined charge pump and regulator solution is required for low-power applications. Ensure the input voltage range aligns with the system's available power source. Consider the 100mA output limit and 25kHz switching frequency for noise-sensitive designs. Verify thermal requirements for the operating environment.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1054 belongs to Texas Instruments' legacy line of switched-capacitor voltage converters. This family provides compact solutions for generating voltages different from the input rail without using inductors. The CDW variant represents the standard commercial grade version in a plastic small-outline package.
