LTC1266AIS#TRPBF

DC DC Switching Controllers Overview

The LTC1266AIS#TRPBF is a synchronous switching regulator controller manufactured by Analog Devices Inc., designed for driving external N- or P-channel MOSFETs. It supports Buck and Boost topologies with a fixed output voltage of 5 V and an output current capability of 700 mA. The device operates at a switch frequency of 400 kHz within an industrial temperature range of -40°C to +85°C. Packaged in a 16-SOIC surface-mount format, it integrates automatic burst mode operation to maintain high efficiency under low load conditions.

DC DC Switching Controllers Feature Summary

• Synchronous control architecture supporting both N-channel and P-channel external power MOSFETs
• Automatic burst mode operation to sustain high efficiency during low output current conditions
• Integrated enable functionality for system power management

DC DC Switching Controllers Applications

• Step-down DC-DC converter designs requiring synchronous rectification
• Power supply systems utilizing P-channel MOSFET configurations
• Battery-powered equipment requiring efficient low-load power management

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the AIS designation corresponds to the industrial temperature grade (-40°C to +85°C). Ensure compatibility with the required 5 V output specification. Check for RoHS compliance status as per current manufacturer declarations. Validate that the 16-SOIC package matches the target PCB footprint requirements.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a dedicated synchronous controller rather than an integrated regulator IC. It is suitable for designs needing flexibility in external MOSFET selection for either N-channel or P-channel topologies. Consider the 400 kHz switching frequency for balancing component size and efficiency. Verify that the 700 mA drive capability meets the gate charge requirements of the chosen power switches.

DC DC Switching Controllers Part Context

This part belongs to the LTC1266 family of synchronous switching regulator controllers from Analog Devices. The family includes variants such as the LTC1266IS-3.3#PBF and LTC1266ACS#TRPBF, which differ primarily in output voltage settings and temperature grades. These devices share the core architecture of driving external MOSFETs with burst mode capabilities for optimized performance across varying load conditions.
