The LT1613CS5#TRM is a versatile Boost, Flyback, and SEPIC DC-DC converter from Linear Technology. It operates from an input voltage as low as 0.9V up to 10V, delivering a switch current of up to 550mA. With a fixed 1.4MHz switching frequency, it enables the use of tiny, low-profile inductors and capacitors, reducing board space. The output voltage can be set from 1.23V to 34V, making it suitable for a wide range of applications including battery-powered devices, portable instruments, and LED drivers. Its compact SOT-23-5 package is ideal for space-constrained designs.
- Wide Input Voltage Range: Operates from 0.9V, enabling use with single-cell batteries and low-voltage sources.
- High Switching Frequency: The 1.4MHz operation allows for smaller external components, saving PCB area.
- Multi-Topology Support: Can be configured as Boost, Flyback, or SEPIC, offering design flexibility.
- Compact Package: The SOT-23-5 Thin package is ideal for space-limited portable applications.
Battery-Powered Devices
With a minimum input voltage of 0.9V, the LT1613CS5#TRM can operate from a single-cell alkaline or NiMH battery, providing a regulated output for portable electronics such as remote sensors and handheld instruments.
Portable Medical Equipment
The high 1.4MHz switching frequency allows for small external components, making it ideal for compact medical devices like glucose meters and portable monitors where space is critical.
LED Drivers
Configured as a boost converter, it can drive strings of white LEDs from a low-voltage source, ensuring consistent brightness in backlighting applications for small displays.
Isolated Power Supplies
In a flyback topology, the LT1613CS5#TRM can generate isolated output voltages for industrial sensors or communication interfaces, simplifying the design of isolated power rails.
SEPIC Converters for Unregulated Inputs
For applications with varying input voltage, such as automotive or battery backup systems, the SEPIC configuration provides a stable output even when the input crosses the output voltage level.
Portable GPS and Tracking Devices
The low quiescent current and wide input range make it suitable for GPS trackers that need to operate efficiently from a small lithium-ion battery over a long duration.
