The LT1373IS8#TRPBF from Analog Devices is a highly versatile current-mode switching regulator. It supports a wide range of topologies including Buck, Boost, Cuk, Flyback, Forward, and SEPIC, making it a flexible solution for many power conversion challenges. Operating from a 2.7V to 30V input, it can generate outputs from 1.245V up to 35V. The internal 1.5A switch and fixed 250kHz switching frequency allow for a compact, efficient design in an 8-SOIC package, ideal for automotive, industrial, and battery-powered systems.
- Ultimate Flexibility: Supports six different topologies, allowing one IC to be used across multiple product designs.
- Wide Input Voltage Range: 2.7V to 30V operation handles a variety of power sources, from batteries to industrial rails.
- High Switching Frequency: 250kHz operation reduces the size of external inductors and capacitors.
- Robust Protection: Current-mode control provides excellent line and load regulation and inherent cycle-by-cycle current limiting.
Multi-Topology Power Supply Design
Its flexibility allows a single design to be adapted for step-down (Buck), step-up (Boost), or inverting (Cuk) applications, reducing design time for varying requirements.
Automotive Power Systems
The wide 2.7V to 30V input range makes it suitable for automotive environments, handling load-dump transients and cold-crank conditions while powering sensors and ECUs.
Industrial 24V Rail Conversion
Efficiently steps down a standard 24V industrial bus to a lower voltage for logic circuits, or steps it up for actuators and valves, using a minimal number of external parts.
Isolated Flyback Power Supplies
Can be used in a flyback configuration to create an isolated, regulated output for telecom or industrial applications, providing galvanic isolation.
Battery-Powered Equipment
With a low 2.7V startup, it can boost a single-cell Li-Ion battery voltage to 3.3V or 5V for portable devices, maximizing battery utilization.
SEPIC for Non-Inverting Buck-Boost
In a SEPIC configuration, it provides a non-inverting output that can be higher or lower than the input, useful for battery-powered devices where voltage varies.
