LT1269CT#PBF

Overview

The LT1269CT#PBF is a high-efficiency switching regulator IC from Analog Devices Inc., housed in a TO-220-5 through-hole package. It supports boost, buck, and buck-boost topologies with an adjustable output voltage up to 60V (switch rating). The device delivers a continuous output current of 4A at a fixed switching frequency of 100kHz. It operates within an input voltage range of 3V to 30V and features a shutdown function. The component functions reliably across a temperature range of 0°C to +125°C.

Feature Summary

Supports multiple converter topologies including step-up, step-down, and combined configurations
Provides high efficiency for stable power rails and DC-DC conversion applications
Includes a dedicated shutdown pin for power management control

Applications

Battery-powered systems requiring flexible voltage regulation
Industrial equipment needing isolated or non-isolated DC-DC conversion
Portable devices utilizing step-up/step-down power architectures

Procurement Notes

Verify the specific suffix and package type against official Analog Devices documentation to ensure compatibility with your design requirements. Confirm RoHS compliance status directly from the manufacturer's datasheet before procurement. Ensure the supplier provides valid traceability documents matching the part number LT1269CT#PBF.

Selection Notes

Select this component when a single IC must handle varying input-output voltage relationships without external topology changes. The TO-220-5 package facilitates thermal dissipation for 4A loads. Consider the 100kHz switching frequency for balancing component size and efficiency needs in space-constrained designs.

Part Context

This part belongs to the LT1268/LT1269 family of monolithic switching regulators. Unlike the LT1268 which is primarily a boost regulator, the LT1269 offers versatile multi-configurational capabilities. It serves as a robust solution for applications demanding both voltage step-up and step-down functionality within a compact integrated circuit form factor.
