LT1054CSW#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054CSW#PBF is a monolithic, bipolar switched-capacitor voltage converter and regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5 V to 15 V and provides an adjustable output voltage up to 30 V with a maximum output current of 100 mA. The device utilizes a charge pump topology and features a switching frequency of 25 kHz. It includes shutdown functionality and maintains a typical total voltage loss of 1.1 V at full load across the supply range. The component is housed in a 16-lead SOIC package and supports operation temperatures from 0°C to +100°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix and manufacturer designation when sourcing replacements, as Texas Instruments produces a functionally similar part (LT1054CDWR) under license. Confirm RoHS compliance status and packaging type (tube vs. tape) against current distributor listings. Ensure the source document explicitly identifies Analog Devices as the manufacturer for this specific part number to avoid confusion with TI equivalents.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a regulated bipolar supply is required from a single unregulated source without using inductors. It is suitable for applications demanding moderate output currents up to 100 mA where low electromagnetic interference is preferred over magnetic converters. Consider the thermal dissipation capabilities of the SOIC-16 package relative to the expected load current and ambient temperature conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LT1054 series of switched-capacitor regulators. It serves as a key solution for generating stable negative or doubled voltages in mixed-signal environments. The series is characterized by its ability to provide higher output currents than earlier generations while significantly reducing voltage drops compared to basic capacitor multiplier circuits.
