LMZ12002 (供給中) 2A SIMPLE SWITCHER Power Module with 20V Maximum Input Voltage

 

概要

The LMZ12002 SIMPLE SWITCHER® power module is an easy-to-use step-down DC-DC solution capable of driving up to 2A load with exceptional power conversion efficiency, line and load regulation, and output accuracy. The LMZ12002 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.

The LMZ12002 can accept an input voltage rail between 4.5V and 20V and deliver an adjustable and highly accurate output voltage as low as 0.8V. The LMZ12002 only requires three external resistors and four external capacitors to complete the power solution. The LMZ12002 is a reliable and robust design with the following protection features: thermal shutdown, input under-voltage lockout, output over-voltage protection, short-circuit protection, output current limit, and allows startup into a pre-biased output. A single resistor adjusts the switching frequency up to 1 MHz.
