The LT1373 is a versatile, current-mode switching regulator from Analog Devices. It supports multiple topologies including Buck, Boost, Cuk, Flyback, Forward, and SEPIC. With a wide 2.7V to 30V input range and a 1.5A internal switch, it provides design flexibility for a variety of applications. Operating at a fixed 250kHz, it balances efficiency with external component size. The 8-lead SOIC package is suitable for space-conscious industrial and automotive designs.
- Multi-Topology Flexibility: Can be used as Buck, Boost, Cuk, Flyback, Forward, or SEPIC, reducing inventory and design effort.
- Wide Input Voltage Range: Operates from 2.7V to 30V, ideal for automotive and industrial power rails.
- High-Voltage Switch: The 42V switch rating supports high-voltage outputs in boost and flyback configurations.
- Fixed 250kHz Operation: Provides a good balance between efficiency and component size, simplifying filter design.
Automotive Power Supplies
The wide 2.7V to 30V input range makes the LT1373 ideal for automotive environments, handling cold-crank and load-dump conditions. It can generate regulated rails for sensors, ECUs, and infotainment systems.
Industrial 24V Rail Conversion
In industrial control systems operating from 24V supplies, the LT1373 can step down to logic voltages or step up for actuator supplies. Its multiple topologies offer design flexibility for various output requirements.
Isolated Flyback Power Supplies
The LT1373's flyback capability enables simple, isolated power delivery for RS-485 transceivers, CAN bus interfaces, and other isolated communication circuits in noisy factory environments.
Battery-Powered Equipment
With a low 2.7V startup, the LT1373 can efficiently boost single-cell or multi-cell battery voltages to 3.3V, 5V, or higher for portable instruments, wireless sensors, and handheld tools.
SEPIC Converters for Variable Inputs
For applications where the input voltage can be above or below the output, the SEPIC topology using the LT1373 provides a non-inverting output with a wide input range, ideal for automotive and battery backup systems.
