The LT1767EMS8E is a versatile current mode step-down DC-DC converter from Analog Devices, offering an adjustable output from 1.2V to 22.5V. It operates from a wide 3V to 25V input supply and delivers up to 1.5A of load current. The 1.25MHz switching frequency allows for a compact solution using small inductors and capacitors. Its high efficiency and low quiescent current make it suitable for battery-powered applications. The converter can also be configured as a SEPIC to handle input voltages that vary above or below the output. Housed in an 8-lead MSOP package with exposed pad, it is ideal for space-constrained industrial, automotive, and portable electronics.
- Adjustable Output (1.2V to 22.5V): Provides maximum design flexibility for various voltage rails without changing the IC.
- Wide Input Range (3V to 25V): Supports a broad range of power sources, from single-cell batteries to 24V industrial supplies.
- 1.5A Output Current: Delivers sufficient power for a wide variety of loads, including processors and sensors.
- 1.25MHz Switching Frequency: Enables small external components, reducing PCB area and cost.
- SEPIC Capability: Allows for non-inverting buck-boost operation, simplifying designs where input voltage can be higher or lower than the output.
Adjustable Power Supplies for FPGAs and DSPs
The adjustable output from 1.2V to 22.5V allows designers to power core logic, I/O, and analog rails in FPGAs and DSPs from a single 3V-25V input, optimizing efficiency per rail.
Automotive Infotainment and ADAS
With a wide input range up to 25V, it can regulate various voltages for infotainment processors, camera modules, and radar sensors, handling load dumps and cold-crank conditions.
Industrial Sensor Interfaces
Provides clean, regulated voltages for precision analog sensors, ADCs, and DACs in industrial process control, ensuring accurate measurements in noisy environments.
Portable Instrumentation
High efficiency and low quiescent current extend battery life in handheld multimeters, data loggers, and portable medical devices, while the small MSOP package saves space.
