LMR51430XDDCR Description

Short technical summary and product information.

The LMR51430XDDCR from Texas Instruments is a versatile synchronous buck converter designed for industrial applications. It operates with an input voltage range from 4.5V to 36V and supports a continuous output current of up to 3A. This device is suitable for power conditioning from unregulated sources.

 

The converter features fixed switching frequency options of 500kHz and 1.1MHz, allowing for optimized solution size with smaller inductors. It offers both PFM mode for high light-load efficiency and FPWM mode for constant frequency operation and reduced output voltage ripple. Internal compensation and soft-start circuits minimize the need for external components.

 

Built-in protection features include cycle-by-cycle current limit, hiccup mode short-circuit protection, and thermal shutdown. The LMR51430XDDCR is housed in a compact SOT-23-6 Thin package, suitable for surface mounting.

 

Applications include appliances, building automation, motor drives, and general-purpose wide VIN power supplies.
