The LT1373CN8#PBF from Analog Devices is a versatile, 250kHz monolithic switching regulator. It can be configured as a buck, boost, Cuk, flyback, forward, or SEPIC converter, offering maximum design flexibility. Operating from a 2.7V to 30V input, it features a 1.5A switch and an adjustable output from 1.245V up to 35V. This makes it an excellent choice for a wide range of applications, from battery-powered portable devices to industrial power supplies requiring multiple topologies.
- Topology Flexibility: Supports buck, boost, Cuk, flyback, forward, and SEPIC configurations, reducing the need for multiple different ICs.
- Wide Input Range: Operates from 2.7V to 30V, accommodating various power sources including batteries and industrial rails.
- High Switching Frequency: The 250kHz frequency allows for smaller external components compared to lower-frequency regulators.
- Robust Switch: The internal 1.5A switch can handle a variety of power levels, making it suitable for many mid-power applications.
Multi-Topology Power Supplies
Its flexibility to be configured as a boost, buck, or SEPIC converter makes it a single solution for various power supply needs in a lab or prototyping environment.
Battery-Powered Systems
With a low 2.7V minimum input, it can boost a single-cell or two-cell battery voltage to a regulated 3.3V or 5V rail for portable instruments.
Isolated Flyback Supplies
Can be used in a flyback topology to create an isolated output for industrial sensors, motor drives, or communication interfaces, providing galvanic isolation.
Negative Output Generation (Cuk)
The Cuk topology allows for generating a negative output voltage from a positive input, useful for op-amp and audio applications.
Automotive Auxiliary Supplies
Its wide input range (up to 30V) makes it suitable for generating auxiliary voltages in automotive systems, such as sensor bias or logic supplies.
High-Voltage Bias Supplies
Can boost a low voltage to a higher voltage (up to 35V) to bias LCD displays, avalanche photodiodes, or other high-voltage components.
