National Semiconductor Corp. (Santa Clara, CA) introduced three SIMPLE SWITCHER® power modules to drive high output voltage applications in a variety of markets including industrial and communications infrastructure. The power modules provide the efficiency of a synchronous switching regulator with the simplicity of a linear regulator.
The easy-to-use LMZ14201H, LMZ14202H, and LMZ14203H accept an input voltage rail between 6V and 42V and deliver an adjustable and highly accurate output voltage up to 24V. A single resistor adjusts the switching frequency to enable greater flexibility of design.
The LMZ14201H, LMZ14202H and LMZ14203H drive loads from 1A to 3A and are well-suited to generate intermediate bus voltages in systems using a distributed point of load (POL) architecture. High efficiency and excellent thermal performance make the modules ideal for systems without airflow.
