The Texas Instruments LM2642MTCX/NOPB is a versatile two-phase peak current mode synchronous buck controller. It is designed to operate with an input voltage range of 4.5V to 30V, making it suitable for a variety of power supply applications.
Key electrical specifications include a maximum output current of 6A, a maximum output voltage of 27V, and a minimum output voltage of 1.238V. The controller utilizes current mode control and features adjustable current limit, phase interleaving, and power good monitoring. It operates with a typical quiescent current of 0.001A and has a maximum duty cycle of 98%.
This device is housed in a 28-TSSOP package, suitable for surface mount applications. The operating temperature range is -40°C to 125°C. Features such as independent enable/soft-start pins allow for sequential startup configuration, and it can be configured for single output parallel operation. Additional protections include input under-voltage lockout, output over-voltage latch protection, and thermal shutdown.
The LM2642MTCX/NOPB is targeted for embedded systems and console/set-top box applications where efficient and reliable power conversion is required.
