The LT1372HVIS8#TRPBF is a highly versatile 500kHz monolithic switching regulator 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 features an adjustable output with a 1.245V reference and a 42V switch rating. The 1.5A internal switch and high frequency operation enable compact, efficient power solutions for a vast array of applications, from battery-powered portable devices to industrial power supplies.
- Ultimate Design Flexibility: Supports six different topologies (Buck, Boost, Cuk, Flyback, Forward, SEPIC) with a single IC, simplifying inventory and design.
- Wide Input and Output Range: Operates from 2.7V to 30V input and can switch up to 42V, accommodating diverse power requirements.
- High-Frequency Operation: The 500kHz switching frequency allows for small external components, resulting in a compact power supply footprint.
- High-Efficiency Conversion: The current-mode architecture ensures excellent line and load regulation with high efficiency across various topologies.
Multi-Topology Power Supply Design
Use the same IC for buck, boost, or SEPIC designs, reducing inventory and design effort across multiple product lines with different power requirements.
Boost for Battery-Powered LED Drivers
Boost a single-cell Li-Ion voltage (2.7V-4.2V) to drive high-brightness LEDs in series, requiring up to 42V, for portable lighting and backlighting.
Flyback for Isolated Supplies
Create a compact, isolated power supply for industrial sensors or gate drivers using the flyback topology, leveraging the 42V switch rating.
SEPIC for Automotive Load-Dump Protection
Implement a SEPIC converter to provide a regulated output that is immune to input voltage drops and surges common in automotive electrical systems.
Negative Output (Cuk) for Audio/Op-Amps
Generate a negative supply rail from a positive input using the Cuk topology, ideal for powering operational amplifiers and audio circuits.
Wide-Input Industrial Logic Supply
Step down a wide-ranging industrial supply (5V to 30V) to a stable 3.3V or 5V logic rail for microcontrollers and digital systems.
