LT1054CN8#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054CN8#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 delivers an output current of 100 mA. The device features an adaptive switch driver scheme that optimizes efficiency across wide output current ranges. Total voltage loss at 100 mA output is typically 1.1 V, consistent across the full supply voltage range. Key electrical parameters include a switching frequency of 25 kHz, a maximum operating temperature of +100 C, and a load regulation of 50 mV.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Monolithic bipolar switched-capacitor architecture providing integrated voltage conversion and regulation capabilities.
• Adaptive switch driver scheme designed to optimize efficiency over a wide range of output currents.
• Significantly reduced voltage losses compared to previous converter generations while maintaining higher output current.

Voltage Regulators - DC DC Switching Regulators Applications

• Negative voltage doubler with regulation
• Positive voltage doubler with regulation
• Basic voltage inverter and regulator circuits
• Digitally programmable negative power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the PDIP-8 through-hole package requirement against PCB layout constraints. Ensure the 3.5 V to 15 V input range aligns with system power rails. Cross-reference the 100 mA output current limit with peak load demands to prevent thermal or performance issues during operation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a single-supply switched-capacitor solution capable of generating inverted or doubled voltages. The PDIP-8 package suits prototyping or low-volume through-hole designs. Consider the 25 kHz switching frequency for noise-sensitive environments where lower frequencies are preferred. Verify that the 1.1 V typical voltage drop meets the headroom requirements of the downstream circuitry under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1054 series represents a family of switched-capacitor converters from Analog Devices. The CN8 variant specifically denotes the commercial temperature grade (0 C to +70 C ambient, though junction extends to 100 C) housed in an 8-pin PDIP package. This part serves as a direct replacement for older charge pump ICs requiring higher current capability and improved efficiency without external inductors.
