LTC1266IS-5#TRPBF

DC DC Switching Controllers Overview

The LTC1266IS-5#TRPBF 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 using N-channel or P-channel MOSFETs. The device features a fixed 400 kHz switching frequency and provides a regulated 5 V output with a maximum current capability of 700 mA. Operating within a supply voltage range of 3.5 V to 18 V, it functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a compact 16-SOIC surface-mount format, this component integrates essential control logic for power management applications requiring precise voltage regulation.

DC DC Switching Controllers Feature Summary

• Supports synchronous rectification for both N-channel and P-channel MOSFET configurations
• Enables flexible circuit design through compatible Buck and Boost topology operations
• Integrates internal oscillator for stable 400 kHz switching frequency performance

DC DC Switching Controllers Applications

• Battery-powered portable electronic devices requiring efficient step-down conversion
• Industrial control systems utilizing standard 5 V logic levels
• Communication equipment power supplies needing compact form factors

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status as manufacturing processes may evolve. Check current lifecycle status since availability varies by region. Ensure supplier documentation matches the exact part number to avoid pinout mismatches. Validate operating temperature ranges against your specific environmental requirements before finalizing procurement decisions.

DC DC Switching Controllers Selection Notes

Choose this controller when designing circuits that require synchronous rectification for improved efficiency. It is suitable for applications needing a fixed 5 V output without external feedback resistors. Consider the 16-SOIC package size for space-constrained PCB layouts. Evaluate the 400 kHz frequency against EMI constraints and inductor size requirements. Ensure input voltage stays within the 3.5 V to 18 V operational window for reliable performance.

DC DC Switching Controllers Part Context

This component belongs to the LTC1266 family of synchronous regulator controllers. Variants like the LTC1266IS-3.3#PBF offer different fixed output voltages while sharing similar control architectures. The series is categorized under PMIC switching voltage regulators. These controllers are designed to simplify power supply design by integrating gate drive capabilities and protection features into a single IC solution.

DC DC Switching Controllers Replacement Considerations

LTC1266IS-3.3#TRPBF serves as a functional substitute if a 3.3 V output is acceptable instead of 5 V. Other LTC1266 variants share identical pinouts and control logic but differ in fixed output voltage settings. Verify that any replacement maintains the same SOIC-16 package dimensions and thermal characteristics for direct board compatibility.
