LT1111CS8#PBF

Overview

The LT1111CS8#PBF is a micropower DC/DC converter manufactured by Analog Devices Inc., housed in an 8-SOIC package. It supports both buck and boost topologies with an input voltage range of 2 V to 30 V. The device provides an adjustable output voltage starting from 1.25 V, capable of reaching up to 50 V in switch mode. It delivers a maximum output current of 1.5 A and operates at a fixed switching frequency of 72 kHz. Quiescent current is specified at 300 uA, and the component functions within a temperature range of 0°C to +70°C.

Feature Summary

Supports both step-down (buck) and step-up (boost) conversion topologies for flexible power management.
Provides an adjustable output voltage range beginning at 1.25 V to accommodate various load requirements.
Operates with low quiescent current consumption suitable for battery-powered applications.
Delivers high output current capability through a compact surface-mount package.

Applications

Portable instrumentation requiring efficient voltage regulation
Battery-powered systems needing extended operational life
Industrial control circuits utilizing standard logic levels
Embedded systems with variable input supply conditions

Procurement Notes

Verify the specific suffix and packaging configuration against the official datasheet before ordering. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any recent product change notices regarding material or electrical parameter updates. Validate compatibility with your system's input voltage constraints.

Selection Notes

Choose this component when both buck and boost capabilities are required from a single regulator. Consider the 1.5 A output current limit for load sizing. Evaluate the 72 kHz switching frequency for electromagnetic interference considerations. Assess the 300 uA quiescent current impact on standby power budgets. Verify that the 2 V minimum input voltage aligns with your source supply characteristics.
