Voltage Regulators - DC DC Switching Regulators datasheet and documents for LT1054IPG4

LT1054IPG4

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054IPG4 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 up to 100 mA output current. The device supports adjustable or fixed output voltages, including configurations for -Vin and 2Vin ratios, with a maximum output voltage of 26.4 V. It utilizes a charge pump topology with a switching frequency of 25 kHz. The component is housed in a 16-SOIC package (0.295 inch width) and is rated for operation 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 combined voltage conversion and regulation.
Supports flexible output configurations including positive, negative, and adjustable voltage levels.
Features low quiescent current consumption suitable for battery-powered applications.

Voltage Regulators - DC DC Switching Regulators Applications

Portable instrumentation requiring dual polarity supplies
RS-232 transceiver power supply generation
Battery-operated systems needing voltage inversion or multiplication

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'IPG4' against official Texas Instruments documentation to confirm pinout compatibility and thermal characteristics. Ensure the procurement channel provides valid traceability for RoHS compliance. Cross-reference the manufacturer part number with the latest datasheet revision to confirm availability status, as older variants may be subject to discontinuation notices.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-chip solution for both voltage conversion and regulation is required. It is appropriate for designs needing isolated negative rails or boosted voltages from a single low-voltage source. Consider the 100 mA current limit and 25 kHz switching frequency when evaluating electromagnetic interference constraints and output ripple requirements relative to the application load.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1054 belongs to the family of switched-capacitor voltage converters produced by Texas Instruments and formerly Linear Technology. These devices are designed to replace bulky transformers or inductors in compact power systems. The IPG4 designation indicates a specific industrial-grade temperature range and lead-free packaging configuration within the broader LT1054 product line.
