Texas Instruments' LMZ1420x SIMPLE SWITCHER® power modules are an easy-to-use DC-DC solution capable of driving up to a 3 A load with exceptional power conversion efficiency, output voltage accuracy, and line and load regulation. They are available in an innovative package that enhances thermal performance and allows for hand or machine soldering.
The LMZ14201/2/3 can accept an input voltage rail between 6 V and 42 V. The devices can deliver an adjustable and highly accurate output voltage as low as 0.8 V and as high as 6 V. The control structure is constant on-time with input voltage feed forward. This creates a nearly constant switching frequency across the input voltage range.
