The LT1376HVIS is a high-voltage, current-mode PWM Buck DC-DC converter from Analog Devices. It accepts an input from 5V to 30V and provides an adjustable output from 2.42V to 25.8V. The internal 1.5A switch and fixed 500kHz switching frequency enable a compact, efficient power solution. Its high input voltage capability makes it ideal for automotive and industrial applications. It can also be configured as a SEPIC converter for applications where the output may be above or below the input.
- High Input Voltage (30V): Directly handles automotive and industrial voltage transients without requiring external protection circuitry.
- Current-Mode Control: Provides excellent line and load regulation, as well as fast transient response, ensuring stable output under dynamic loads.
- 500kHz Fixed Frequency: Allows for small, low-cost inductors and capacitors, reducing the overall solution size and cost.
- Versatile Buck or SEPIC Topology: Offers design flexibility to address both step-down and step-up/step-down applications with a single IC.
Automotive Power Supplies
In automotive systems, the LT1376HVIS's 30V input rating handles load-dump transients, providing a regulated 5V or 3.3V rail for engine control units, sensors, and infotainment systems from the 12V battery bus.
Industrial Control Systems
For industrial PLCs and motor controllers operating from 24V rails, this converter steps down to logic voltages with high efficiency. Its 500kHz frequency allows for small external components, saving PCB space.
SEPIC for Wide-Range Inputs
When configured as a SEPIC, the LT1376HVIS can regulate an output voltage that is above or below the input. This is useful in applications where the input voltage is not well-defined, such as in automotive cold-crank or battery backup systems.
Distributed Power Architectures
In systems with a 12V or 24V intermediate bus, the LT1376HVIS provides a local, point-of-load supply for FPGAs, ASICs, or microcontrollers, reducing noise and improving regulation.
Networking and Telecom Equipment
For networking switches and routers, this converter can generate a clean 3.3V or 2.5V rail from a 12V backplane, powering high-speed logic and interface circuits with minimal ripple.
Battery Chargers
The LT1376HVIS can be used as a constant-current/constant-voltage battery charger for lead-acid or Li-Ion batteries, leveraging its current-mode control and adjustable output voltage.
