The LM5642XMTX/NOPB from Texas Instruments is a high-performance, power-efficient product that is part of TI's extensive line of power management integrated circuits (ICs) designed to manage, control, and distribute power in a variety of electronic devices.

• Key Features:
• Dual step-down DC/DC converter, designed to convert a higher DC voltage to a lower DC voltage efficiently
• Operates at a frequency of 1 MHz, allowing for the use of small surface mount inductors and capacitors
• Handles a wide input voltage range of 4.5V to 28V
• High power output capability, with each of its two outputs capable of delivering up to 2A of continuous output current
• Adjustable soft-start function prevents inrush current during startup, protecting the device and prolonging its lifespan
• Under-voltage lockout (UVLO) feature shuts down the device when the input voltage falls below a preset threshold, preventing damage due to low voltage conditions
• 28-pin HTSSOP package is lead (Pb) free and green (RoHS compliant)
• Power pad on the underside of the package for enhanced thermal performance
