LTC1266ACS#PBF

DC DC Switching Controllers Overview

The LTC1266ACS#PBF is a synchronous switching regulator controller manufactured by Analog Devices Inc., designed for high-efficiency DC-DC conversion. It supports both buck and boost topologies, making it versatile for various power management applications. The device operates with an input voltage range of 3.5 V to 20 V and features a fixed switching frequency of 400 kHz. It provides a maximum output current capability of 700 mA and includes a shutdown feature for power conservation. The component is housed in a 16-SOIC package and is rated for commercial operating temperatures between 0°C and +70°C.

DC DC Switching Controllers Feature Summary

• Synchronous control architecture supporting N-channel or P-channel MOSFETs for improved efficiency
• Flexible topology support enabling implementation of both step-down (buck) and step-up (boost) converters
• Integrated shutdown functionality to minimize quiescent current during standby modes

DC DC Switching Controllers Applications

• Portable battery-powered equipment requiring efficient voltage regulation
• General-purpose DC-DC power supply designs
• Embedded systems needing stable voltage rails from varying input sources

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS 3 status before procurement. Confirm the commercial temperature grade (0°C to +70°C) aligns with your system's environmental requirements. Ensure the 16-SOIC package dimensions fit your PCB layout constraints. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

DC DC Switching Controllers Selection Notes

Select this controller when designing circuits that require both buck and boost capabilities within a single component. Consider the 400 kHz switching frequency for balancing component size and efficiency. Evaluate the 700 mA output limit against your load requirements. The SOIC-16 package offers a balance of thermal performance and board space efficiency compared to larger packages.

DC DC Switching Controllers Part Context

This component belongs to the LTC1266 family of synchronous regulators from Analog Devices. It is distinct from non-synchronous controllers by its ability to drive both high-side and low-side switches, reducing conduction losses. The ACS variant specifies the commercial temperature range, differentiating it from industrial or military grades which may offer wider operational limits.

DC DC Switching Controllers Replacement Considerations

Direct replacements include other LTC1266 variants such as the LTC1266IS-3.3#PBF for industrial temperature ranges or the LTC1266CS#PBF. Verify pin compatibility and electrical specifications when substituting. Note that suffix changes may indicate differences in temperature rating or packaging rather than functional alterations.
