The LT1376IS#PBF from Analog Devices is a versatile 500kHz monolithic buck and SEPIC switching regulator. It accepts input voltages from 5V to 25V and delivers up to 1.5A of switch current, with an adjustable output from 2.42V to 21.5V. Its high switching frequency allows for small, low-cost inductors and capacitors, while the current mode topology provides fast transient response and excellent loop stability. Ideal for battery-powered systems, industrial controls, and distributed power architectures, this regulator combines high efficiency with a compact 16-pin SOIC package.
- High Frequency Operation (500kHz): Enables smaller external components, reducing PCB area and overall solution cost.
- Wide Input Range (5V to 25V): Accommodates a variety of unregulated supplies, including 12V and 24V rails.
- Buck and SEPIC Topology: Offers design flexibility for step-down or inverting/step-up/down applications.
- 1.5A Switch Current: Provides sufficient current capability for a wide range of medium-power loads.
Battery-Powered Industrial Equipment
With a wide 5V to 25V input range and 500kHz switching frequency, the LT1376IS#PBF efficiently regulates battery voltages in portable industrial tools, extending runtime while minimizing external component size.
SEPIC Converters for Unregulated Power Rails
Its SEPIC capability allows the output voltage to be above or below the input, making it ideal for systems with loosely regulated supplies, such as automotive or telecom rails that vary widely.
Distributed Power Systems
The 1.5A switch current and high frequency operation enable compact point-of-load converters in distributed power architectures, reducing board space in networking and server equipment.
Positive-to-Negative Converters
The LT1376IS#PBF can be configured as a positive-to-negative converter, providing a regulated negative rail for analog circuits, op-amps, and audio applications from a positive supply.
High Voltage Step-Down for Automotive
Handling inputs up to 25V, this regulator can step down 12V or 24V automotive battery voltages to logic levels, powering microcontrollers and sensors in engine control units.
Telecom Line Cards
Its 500kHz fixed frequency simplifies EMI filtering, making it suitable for telecom line cards where noise-sensitive analog and digital circuits coexist on the same board.
