LM2642MTCX Description

Short technical summary and product information.

The Texas Instruments LM2642MTCX is a two-phase peak current mode synchronous buck controller designed for efficient power management.

 

This controller supports a wide input voltage range from 4.5V to 30V, making it suitable for various applications. It can deliver a maximum output current of 6A and provides adjustable output voltages from 1.238V to 27V. Key features include adjustable current limit, phase interleaving for reduced ripple, and a power good function. The device operates with a typical quiescent current of 1mA and a shutdown current of 37µA.

 

Packaged in a 28-TSSOP, the LM2642MTCX is designed for surface mount applications. Its operating temperature range is -40°C to 125°C. The controller utilizes current mode control and offers features like independent enable/soft-start pins for sequential startup and configurable single output parallel operation.

 

This component is well-suited for embedded systems and console/set-top box applications requiring robust and efficient step-down voltage conversion.
