LMZ12002 电源模块 可调哦

　　The LMZ12002 SIMPLE SWITCHER® power module APPLICATIONS is an easy-to-use step-down DC-DC solution capable

　　• Point of Load Conversions from 5V and 12V of driving up to 2A load with exceptional power

　　Input Rail conversion efficiency， line and load regulation， and

　　output accuracy. The LMZ12002 is available in an

　　• Time Critical Projects innovative package that enhances thermal

　　• Space Constrained High Thermal Requirement performance and allows for hand or machine

　　Applications soldering.

　　• Negative Output Voltage Applications The LMZ12002 can accept an input voltage rail

　　（See AN-2027） 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 overvoltage 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
