The LT1372IN8 is a highly flexible DC-DC converter IC from Analog Devices, capable of operating in Buck, Boost, Cuk, Flyback, Forward, and SEPIC configurations. It accepts a wide input voltage from 2.7V to 30V and can generate outputs from 1.245V up to 35V, with a 1.5A switch current limit. The 500kHz switching frequency enables compact transformer and inductor sizes. This versatility makes it a go-to choice for engineers designing battery-powered, automotive, or isolated power systems.
- Universal Topology Support: One IC for Buck, Boost, Cuk, Flyback, Forward, and SEPIC designs.
- Ultra-Wide Input Range (2.7V-30V): Works from low-voltage batteries to 24V industrial rails.
- High Output Voltage Capability (up to 35V): Suitable for LED drivers, displays, and high-voltage rails.
- 500kHz Switching Frequency: Minimizes transformer and inductor size, saving board space.
Multi-Topology Power Design
The LT1372IN8's support for Buck, Boost, Cuk, Flyback, Forward, and SEPIC topologies makes it a single solution for diverse power requirements. Designers can use it to create step-down, step-up, or isolated supplies with one part.
Low-Voltage Battery Boost
With a minimum input of 2.7V, this converter can boost a single-cell Li-Ion or 2-cell alkaline battery to higher voltages (e.g., 5V or 12V) for portable devices, LED drivers, or small displays.
Isolated Flyback Power Supplies
In Flyback mode, the LT1372IN8 can provide isolated outputs for industrial sensors, gate drivers, or communication interfaces. The 500kHz frequency reduces transformer size, enabling compact isolated supplies.
Automotive Wide-Input Applications
The 2.7V to 30V input range covers automotive cold-crank and load-dump conditions. It can be used to generate regulated rails for infotainment, ADAS, or body control modules.
SEPIC for Stable Output from Fluctuating Input
In SEPIC mode, it provides a regulated output even when the input voltage crosses the output threshold, making it ideal for battery-powered equipment where voltage decays over time.
