The Analog Devices LT1376IS#TRPBF is a 500kHz monolithic buck switching regulator capable of delivering 1.5A from an internal switch. It accepts inputs from 5V to 25V and provides an adjustable output from 2.42V to 21.5V. The high switching frequency allows for small, low-cost inductors and capacitors. This versatile IC can also be configured as a SEPIC converter for generating negative rails. It is ideal for a wide range of applications including industrial, telecom, and portable battery-powered systems.
- 500kHz Fixed Frequency: Enables small external components, reducing PCB area and cost.
- SEPIC Capability: Offers design flexibility to generate negative or higher-voltage outputs from a positive input.
- 1.5A Internal Switch: Provides sufficient current for a wide range of medium-power applications without external FETs.
- Wide Output Range (2.42V-21.5V): Supports multiple voltage rails with a single design.
Positive-to-Negative Converters (SEPIC)
The LT1376's ability to operate as a SEPIC converter allows generation of a negative rail from a positive input, useful in op-amp and audio applications requiring dual supplies.
5V to 3.3V Point-of-Load Regulation
Efficiently steps down a 5V logic rail to 3.3V for microcontrollers and DSPs. The 500kHz frequency allows for small inductors, saving board space in compact designs.
Battery-Powered Portable Instruments
With a 5V minimum input, it can regulate from a 4-cell NiMH or single Li-ion battery pack (boosted) to a stable 3.3V or 5V rail, maximizing battery utilization.
Industrial Sensor Interfaces
Provides a clean, regulated supply for sensors and transducers operating from a 12V or 24V industrial bus. The high switching frequency reduces output ripple, improving measurement accuracy.
Telecom Line Cards
Converts a 12V backplane supply to a local 5V rail for line driver and receiver circuits. The 1.5A switch current is sufficient for multiple channels.
Automotive Accessory Power
Regulates power for aftermarket accessories from a 12V car battery. The 25V max input handles typical automotive transients without external clamping.
