The LTC1265CS#PBF from Analog Devices is a high-efficiency Buck DC-DC converter with versatile topology options, including Buck-Boost and SEPIC. It operates from a 4V to 13V input and delivers an adjustable output from 1.25V to 13V, with a 1.2A switch current. The switching frequency extends up to 700kHz, allowing for small external components. Housed in a 14-SOIC package, it is suitable for automotive, industrial, and telecom power supplies.
- Multi-Topology Support: Can be configured as Buck, Buck-Boost, or SEPIC for design flexibility.
- Wide Output Range: 1.25V to 13V covers logic, I/O, and analog rails.
- High Frequency Operation: Up to 700kHz reduces inductor and capacitor sizes.
- Robust Package: 14-SOIC is widely available and easy to solder.
Automotive Power Supplies
With a 4V-13V input range, the LTC1265CS#PBF can regulate 5V or 3.3V rails from a car battery (9V-16V with transients), powering ECUs and sensors.
Industrial Control Systems
For 12V industrial buses, this buck converter provides a stable 5V rail for microcontrollers and logic circuits, with up to 1.2A of current.
Telecom and Networking Equipment
In 12V-powered networking gear, the LTC1265CS#PBF steps down to 3.3V or 2.5V for FPGAs and ASICs, with high efficiency to reduce heat.
Battery Chargers
The buck-boost or SEPIC configurations allow charging a battery from a varying input source, such as a solar panel or unregulated wall adapter.
Distributed Power Architectures
As a point-of-load converter, it takes a 5V or 12V intermediate bus and provides a clean, regulated low-voltage rail close to the load.
Portable Instruments
For devices powered by 6-12V adapters, this converter efficiently generates a 3.3V or 5V rail, supporting battery charging and system power.
