SIMPLE SWITCHER® 6V to 42V, 1A Power Module in Leaded Surface Mount TO Package

SIMPLE SWITCHER® 6V to 42V, 1A Power Module in Leaded Surface Mount TO Package - LMZ14201
 

Description

The LMZ14201 SIMPLE SWITCHER® power module is an easy-to-use step-down DC-DC solution that can drive up to 1-A load with exceptional power conversion efficiency, line and load regulation, and output accuracy. The LMZ14201 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.

The LMZ14201 can accept an input voltage rail between 6 V and 42 V and deliver an adjustable and highly accurate output voltage as low as 0.8 V. The LMZ14201 only requires three external resistors and four external capacitors to complete the power solution. The LMZ14201 is a reliable and robust design with the following protection features: thermal shutdown, input UVLO, output overvoltage protection, short-circuit protection, output current limit, and allows start-up into a prebiased output. A single resistor adjusts the switching frequency up to 1 MHz.
