LT1110CS8#PBF

Overview

The LT1110CS8#PBF is a micropower DC-DC converter manufactured by Analog Devices Inc., housed in an 8-pin SOIC package. It operates with input voltages ranging from 1 V to 30 V and supports both step-up and step-down topologies. The device delivers a single adjustable output with a maximum current of 1 A, utilizing an internal power switch. Key electrical parameters include a quiescent current of 300 µA and a switching frequency of 70 kHz. It functions within a temperature range of 0°C to +70°C.

Feature Summary

Operates as a versatile micro-power DC-DC converter requiring only three external components for fixed or adjustable output configurations.
Features an on-chip auxiliary gain block that functions as a low-battery detector or linear post regulator.
Includes an internal user-adjustable current limit and a 1 A power switch for robust protection.

Applications

Single cell battery to 5V DC-DC conversion
1.5V powered laser diode drivers
Remote or battery-powered applications requiring minimal current consumption

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm availability status as distribution channels may report limited stock or discontinuation. Ensure the SOIC-8 package matches your PCB footprint requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm pinout and electrical specifications before integration.

Selection Notes

Select this component for applications requiring wide input voltage ranges down to 1 V. It is suitable for designs needing simple implementation with minimal external parts. Consider the 70 kHz switching frequency for component size trade-offs. Evaluate the 300 µA quiescent current against system power budgets for battery-operated devices.

Part Context

This part belongs to the LT1110 series of micropower DC-DC converters. It is designed for space-constrained environments using the 8-pin MiniDIP or S8 package. The series emphasizes low component count and efficiency in low-power conversion scenarios.
