The LMZ14203HTZ is a SIMPLE SWITCHER® 6 to 42V 3A high output voltage Power Module which is an easy-to-use step-down DC-DC solution that can drive up to 3A load with exceptional power conversion efficiency, line and load regulation and output accuracy. The LMZ14203HTZ can accept an input voltage rail between 6 and 42V and deliver an adjustable and highly accurate output voltage as low as 5V. The power module only requires three external resistors and four external capacitors to complete the power solution. This power module is reliable and robust in design with the following protection features thermal shutdown, input under-voltage lockout, output overvoltage protection, short-circuit protection, output current limit and allows start-up into a pre-biased output. A single resistor adjusts the switching frequency up to 1MHz.
● Integrated shielded inductor
● Simple PCB layout
● Flexible start-up sequencing using external soft-start and precision enable
● Protection against inrush currents
● Input UVLO and output short-circuit protection
● Single exposed pad and standard pin-out for easy mounting and manufacturing
● Low output voltage ripple
● High efficiency reduces system heat generation
● No compensation required
●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
